Description

食品切断装置Food cutting equipment
　本発明は、例えば巻き寿司などの棒状の食品を所定の幅に輪切り状に切断する食品切断装置に関するものである。 The present invention relates to a food cutting device that cuts stick-shaped foods such as sushi rolls into a predetermined width.
　スーパーマーケット、コンビニエンスストア、回転寿司店などで提供される例えば巻き寿司などは、自動機によって棒状に成形され、さらに、所定の幅に輪切り状に切断される。棒状の巻き寿司などを包丁によって手作業で輪切りにしていたのでは多大の労力と時間を要するとともに、輪切りの幅寸法がばらつくので、食品切断装置が用いられている。食品切断装置には、固定した切断対象食品に対し切断刃を移動させて切断するものと、固定した切断刃に対し切断対象食品を移動させて切断するものがある。また、切断刃の支持形態によって、片持ち形式のもの、両持ち形式のものに分類することができる。以下、従来の食品切断装置の例について説明する。 For example, rolled sushi provided at supermarkets, convenience stores, carousel sushi restaurants, etc., is formed into a stick shape by an automatic machine, and further cut into a circular shape into a predetermined width. If a stick-shaped sushi roll is manually cut into round pieces with a knife, it takes a lot of labor and time, and the width of the round pieces varies, so a food cutting device is used. There exist some which cut a food cutting device by moving a cutting blade with respect to the fixed cutting blade, and what cuts by moving a cutting target food with respect to the fixed cutting blade. Moreover, according to the support form of a cutting blade, it can classify | categorize into the thing of a cantilever type and the thing of a both-ends type. Hereinafter, an example of a conventional food cutting device will be described.
　特許文献１には、固定した切断対象食品に対し切断刃を回転させながら当てることにより切断対象食品を輪切りにする食品切断装置が記載されている。上記切断刃は、回転軸に対し直交させて固着された複数の切断刃からなり、回転軸に片持ち状に固着された構造、すなわち回転刃になっている。 Patent Document 1 describes a food cutting device that cuts a food to be cut into round pieces by rotating the cutting blade against a fixed food to be cut. The cutting blade is composed of a plurality of cutting blades fixed perpendicularly to the rotating shaft, and has a structure fixed to the rotating shaft in a cantilever manner, that is, a rotating blade.
　特許文献２には、固定した切断対象食品である海苔巻寿司等に対し切断刃を移動させながら当てることにより海苔巻寿司等を輪切りにする海苔巻寿司等の切断装置が記載されている。上記切断刃は、刃物枠に複数平行に配置して長さ方向両端を保持したものすなわち両持ち状にしたもので、刃物枠を複数の切断刃とともにリンク機構により移動させて海苔巻寿司等を切断する構成になっている。 Patent Document 2 describes a cutting device for seaweed roll sushi or the like that cuts seaweed roll sushi or the like in a round shape by moving the cutting blade against the seaweed roll sushi or the like that is a fixed food to be cut. The cutting blades are arranged parallel to the blade frame and held at both ends in the length direction, i.e., are both supported.The blade frame is moved with a plurality of cutting blades by a link mechanism to cut nori sushi rolls, etc. It is configured to do.
　特許文献３には、固定した切断刃に対し切断対象食品である巻き寿司を移動させて切断する巻き寿司の切断装置が記載されている。上記切断刃は、刃物枠に複数平行に配置して長さ方向両端を保持したものすなわち両持ち状にしたもので、上記刃物枠をフレームに固定している。上記巻き寿司はこれを受け台に載せ、この受け台を上方に移動させることにより巻き寿司に切断刃を徐々に食い込ませながら巻き寿司を輪切り状に切断する構成になっている。切断刃を固定し、切断刃に対し対象食品を相対移動させることによって対象食品を輪切り状に切断する食品切断装置は、特許文献４にも記載されている。 Patent Document 3 describes a cutting apparatus for rolled sushi that moves and cuts rolled sushi, which is a food to be cut, with respect to a fixed cutting blade. The cutting blade is a plurality of cutting blades arranged in parallel to the blade frame and held at both ends in the length direction, that is, a both-end supported shape, and the blade frame is fixed to the frame. The above-mentioned rolled sushi is placed on a receiving tray, and the receiving tray is moved upward to cut the rolled sushi into round slices while gradually cutting a cutting blade into the rolled sushi. A food cutting device that cuts a target food in a circular shape by fixing the cutting blade and moving the target food relative to the cutting blade is also described in Patent Document 4.

　特許文献１記載の発明によれば、切断対象食品を載置台に載せ、その場で回転刃の回転により切断する形式になっているから、切断対象食品のセットと切断後の食品の取り出しを同じ位置で行うことができ、作業性は良い。しかし、載置台に載せられた切断対象食品を回転刃が横切るため、切断対象食品を回転刃が横切るときは載置台の周辺に手を差し入れることができないように安全機構を設けて安全性を確保する必要がある。また、切断刃は回転軸に片持ち的に固着されるため、刃の厚みを大きくして所定の強度を持たせる必要があり、切断対象食品に対する切れ味が、両持ち型の切断刃を用いる場合と比較すると若干劣る。したがって、海苔巻き寿司のような柔らかい切断対象食品の場合、切断時に加わる圧力で型崩れを生じることがある。この点、両持ち型の切断刃は、長さ方向両端部で支持されるため、切断刃の厚みを薄くして切れ味を高めることができ、切断対象食品の型崩れを少なくすることができる。 According to the invention described in Patent Document 1, since the food to be cut is placed on the mounting table and cut by the rotation of the rotary blade on the spot, the set of food to be cut and the removal of the food after cutting are the same. It can be performed at the position, and workability is good. However, since the rotary blade crosses the food to be cut placed on the mounting table, a safety mechanism is provided to ensure safety when the rotary blade crosses the food to be cut so that a hand cannot be inserted around the mounting table. It is necessary to secure. In addition, since the cutting blade is cantilevered to the rotating shaft, it is necessary to increase the thickness of the blade to give it a predetermined strength. Is slightly inferior. Therefore, in the case of a soft food to be cut, such as laver roll sushi, the shape may be lost due to the pressure applied during cutting. In this respect, since the double-sided cutting blade is supported at both ends in the length direction, the thickness of the cutting blade can be reduced to improve the sharpness, and the deformation of the food to be cut can be reduced.
　特許文献２記載の発明は、切断対象食品を載置台に載せ、次に切断刃を一方向に移動させることにより切断対象食品を切断し、そのあと切断刃は原位置に向かって復動するようになっている。したがって、切断刃が復動するとき、切断された対象食品が残っていると切断刃が復動する途中で上記対象食品に当たるため、切断した対象食品を載置台から取り出す必要がある。よって、特許文献２記載の発明によれば、切断刃の移動によって切断対象食品を切断した後、対象食品の取り出し操作を行い、次に切断刃の復帰操作を行う必要があり、操作が面倒になる難点がある。 In the invention described in Patent Document 2, the food to be cut is placed on the mounting table, and then the food to be cut is cut by moving the cutting blade in one direction, and then the cutting blade moves backward toward the original position. It has become. Therefore, when the cutting blade moves backward, if the cut target food remains, the cutting blade hits the target food in the middle of the backward movement, so it is necessary to take out the cut target food from the mounting table. Therefore, according to the invention described in Patent Document 2, after cutting the food to be cut by moving the cutting blade, it is necessary to perform an operation for taking out the target food and then to perform a return operation of the cutting blade, which is troublesome. There is a difficult point.
　特許文献３および特許文献４記載の発明によれば、切断対象食品である巻き寿司を載せた受け台を移動させて切断刃により巻き寿司を切断したあと、受け台を原位置まで復帰させるためには、その前に、切断された巻き寿司を受け台から取り出す必要がある。そうしなければ、切断された巻き寿司が原位置に戻ってしまい、また、戻る途中で、切断された巻き寿司に切断刃が当たるからである。したがって、巻き寿司を切断した後、巻き寿司の取り出し操作を行い、次に切断刃の復帰操作を行う必要があり、操作が面倒になる。また、装置を稼働させるためのスイッチ操作は、巻き寿司を切断するために受け台を移動させるためのスイッチ操作と、受け台を原位置に復帰させるためのスイッチ操作の２回の操作が必要であり、この点からも操作が面倒になる難点がある。また、装置の下側にある受け台に巻き寿司を載せる操作は、装置の下側にある受け台に対して行うので、操作性の問題はないが、切断された巻き寿司は装置上部の奥側に移動しているため、複数に分離された巻き寿司を取り出すときの作業性が悪いという難点がある。 According to the inventions described in Patent Document 3 and Patent Document 4, after moving the cradle on which the rolled sushi serving as the food to be cut is placed and cutting the rolled sushi with the cutting blade, the cradle is returned to the original position. Before that, it is necessary to remove the cut sushi roll from the cradle. Otherwise, the cut sushi roll returns to the original position, and the cutting blade hits the cut sushi roll on the way back. Therefore, after cutting the rolled sushi, it is necessary to perform an operation to take out the rolled sushi and then perform a return operation of the cutting blade, which is troublesome. In addition, the switch operation for operating the device requires two operations: a switch operation for moving the cradle to cut the rolled sushi and a switch operation for returning the cradle to its original position. There is also a difficulty that the operation becomes troublesome from this point. The operation of placing rolled sushi on the cradle on the lower side of the device is performed on the cradle on the lower side of the device. Since it moves to the side, there exists a difficulty that workability | operativity when taking out the rolled sushi separated into plurality is bad.
　また、海苔巻き寿司のような、表面が切断しにくい海苔で覆われ、内部が柔らかくかつ粘り気のある対象食品を切断するとき、対象食品に対して切断刃を単に押しつけるだけでは円滑な切断ができず、切断対象食品の形が崩れやすい。切断対象食品に対して切断刃を刃の方向に沿って相対的に滑らせながら押しつけると、小さな力で切れ味よく切断することができる。そこで、何れの引用文献記載の発明においても、切断刃が切断対象食品に対して刃の方向に滑りながら押しつけられるように、刃の形、刃の設置姿勢、切断刃に対する受け台の移動方向が工夫されている。 Also, when cutting target foods that are covered with seaweed that is hard to cut, such as seaweed sushi rolls, and the inside is soft and sticky, smooth cutting can be achieved simply by pressing the cutting blade against the target food. The shape of the food to be cut easily collapses. When the cutting blade is pressed against the food to be cut while being relatively slid along the direction of the blade, the food can be cut with a small force. Therefore, in any invention described in any cited document, the shape of the blade, the installation orientation of the blade, and the moving direction of the cradle relative to the cutting blade are adjusted so that the cutting blade is pressed against the food to be cut while sliding in the direction of the blade. It has been devised.
　いま、海苔巻き寿司に限らず、一般的な食品を包丁で切断する場合を想定すると、包丁の刃を食品に押しつけ始めるときは、食品に対する包丁の刃の方向への滑り量を大きくすることによって、包丁の刃を食品内部に円滑に進入させることができる。特に海苔巻き寿司の場合のように、表面が包丁で切りにくい海苔で覆われているものを切断しようとするときは、切断開始当初、包丁を大きく滑らせながら海苔巻き寿司に包丁を押しつけると、包丁の刃が円滑に海苔巻き寿司に食い込み、海苔巻の形崩れがなく、滑らかな切断面を得ることができる。刃が海苔巻き寿司に食い込んだ後は、海苔巻き寿司に対する包丁の相対的な滑り量を小さくしても、海苔巻き寿司を円滑に切断することができる。 Assuming that not only seaweed roll sushi but also general food is cut with a kitchen knife, when you start pressing the knife blade against the food, increase the amount of sliding in the direction of the knife blade against the food. The knife blade can smoothly enter the food. In particular, when trying to cut something covered with seaweed that is difficult to cut with a knife, as in the case of nori roll sushi, when you press the knife against the seaweed roll sushi while sliding the knife greatly, The knife's blade smoothly cuts into the seaweed roll sushi, so that the seaweed roll does not collapse and a smooth cut surface can be obtained. After the blade bites into the seaweed sushi roll, the seaweed sushi roll can be cut smoothly even if the relative sliding amount of the knife relative to the seaweed sushi roll is reduced.
　しかしながら、前述の何れの特許文献記載の発明においても、切断刃が切断対象食品に接して切断を開始してから切断が完了するまで、切断対象食品に対する切断刃の相対的な滑り量がほぼ一定である。特に、巻き寿司を載せた受け台を直線的に移動させてその移動軌跡に直線的に交わる切断刃で巻き寿司を切断するように構成した特許文献３、特許文献４記載の発明によれば、切断開始から終了まで、切断刃に対する巻き寿司の相対移動が終始一定である。このように、切断刃を切断対象食品に当接させて切断を開始するときは、切断対象食品に対して切断刃を大きく滑らせることが望ましいが、前述の何れの特許文献記載の発明においても、切断開始時における切断対象食品に対する切断刃の相対的な滑り速度については考慮されていない。 However, in any of the inventions described in the above-mentioned patent documents, the relative sliding amount of the cutting blade with respect to the cutting target food is substantially constant from when the cutting blade comes into contact with the cutting target food until the cutting is completed. It is. In particular, according to the invention described in Patent Document 3 and Patent Document 4 configured to cut the rolled sushi with a cutting blade that linearly moves the cradle on which the rolled sushi is placed and crosses the movement trajectory linearly. From the start to the end of cutting, the relative movement of the rolled sushi with respect to the cutting blade is constant throughout. As described above, when the cutting blade is brought into contact with the food to be cut and the cutting is started, it is desirable to slide the cutting blade largely with respect to the food to be cut. The relative sliding speed of the cutting blade with respect to the food to be cut at the start of cutting is not considered.
　本発明は、固定した切断刃に対し、対象食品を載せた食品載置台を移動させて対象食品を切断するようにした食品切断装置において、切断開始当初の対象食品への切断刃の進入を容易にして対象食品の変形を低減することを目的とする。 The present invention is a food cutting apparatus in which a food placing table on which a target food is placed is moved relative to a fixed cutting blade to cut the target food, so that the cutting blade can easily enter the target food at the beginning of cutting. It aims at reducing the deformation of the target food.
　本発明は、対象食品を載置する食品載置台と、上記食品載置台を移動させる駆動機構と、上記駆動機構によって上記食品載置台とともに移動させられる上記対象食品の移動軌跡内に固定されていることによって上記対象食品を輪切り状に切断する切断刃と、を有し、上記駆動機構は、対象食品と上記切断刃の接触開始当初は対象食品に対する上記切断刃の進入角度を連続的に変化させることを最も主要な特徴とする。 The present invention is fixed within a movement trajectory of the target food that is moved together with the food placing table by the food mechanism, a food placing table for placing the target food, a driving mechanism for moving the food placing table, and the driving mechanism. A cutting blade that cuts the target food in a circular shape, and the drive mechanism continuously changes the approach angle of the cutting blade to the target food at the beginning of contact between the target food and the cutting blade. This is the main feature.
　本発明によれば、対象食品と切断刃の接触開始当初は、駆動機構が対象食品に対する上記切断刃の進入角度を連続的に変化させるように構成されているため、対象食品を切断刃に対してその刃の方向に迅速に移動させ、切断刃を切れ味鋭く対象食品に食い込ませることができる。したがって、対象食品が変形することなく切断され、滑らかな切断面を得ることができる。 According to the present invention, at the beginning of the contact between the target food and the cutting blade, the drive mechanism is configured to continuously change the approach angle of the cutting blade with respect to the target food. The blade can be quickly moved in the direction of the blade, and the cutting blade can be sharply cut into the target food. Therefore, the target food can be cut without deformation and a smooth cut surface can be obtained.

　以下、本発明に係る食品切断装置の実施例を、図面を参照しながら説明する。 Hereinafter, embodiments of the food cutting device according to the present invention will be described with reference to the drawings.
　図１において、食品切断装置は、上端部が切断対象食品（以下、単に「食品」という）１０の供給部、前面下部が食品１０の排出部となっていて、前面は上記供給部と排出部を除き前面パネル１５で覆われ、左右両側面はそれぞれ側面カバー１４で覆われている。この装置の動作開始前は上記供給部に食品載置台５があり、この食品載置台５に、食品１０、例えば、寿司飯が海苔で巻かれた柱状の海苔巻きを水平方向の姿勢で載置するように構成されている。食品載置台５に食品１０を載置し、スタートスイッチを押すと、食品載置台５が駆動機構によって装置の前側下部に向かって移動させられ、この移動の途中で食品１０が切断刃によって輪切り状に切断され、上記排出部に排出されるように構成されている。排出された食品１０は、食品載置台５から放出されて受け部材８で受け取られ、受け部材８が斜め前下方にスライドし、食品載置台５は駆動機構によって原位置に復帰するように構成されている。 In FIG. 1, the food cutting device has an upper end serving as a supply unit for food to be cut (hereinafter simply referred to as “food”) 10, and a lower front portion serving as a discharge unit for food 10. The left and right side surfaces are covered with side covers 14, respectively. Before the operation of this apparatus is started, there is a food placing table 5 in the supply section, and a columnar nori roll in which food 10, for example, sushi rice is wound with nori is placed on the food placing table 5 in a horizontal posture. Is configured to do. When the food 10 is placed on the food placing table 5 and the start switch is pressed, the food placing table 5 is moved toward the lower front side of the apparatus by the drive mechanism, and the food 10 is cut into a ring shape by a cutting blade during the movement. And is discharged to the discharge portion. The discharged food 10 is discharged from the food placing table 5 and received by the receiving member 8. The receiving member 8 slides obliquely forward and downward, and the food placing table 5 is returned to the original position by the drive mechanism. ing.
　次に、上記食品切断装置の内部構造を詳細に説明する。図１乃至図４において、食品切断装置は、ベース１と、ベース１の左右両端部に結合されて互いに平行に垂直方向に立ち上がった左右の側板４と、各側板４の後端部を連結する背板２０を有していて、これらベース１、左右の側板４および背板２０で食品切断装置の骨格をなしている。装置の前寄りの位置に切断刃固定枠２がほぼ垂直方向の姿勢で配置されている。切断刃固定枠２は、左右の両端縁部が、左右の側板４に上下方向に固定された一対のガイドレールに沿って落とし込まれ、上記ガイドレールにより左右の側板４間に実質的に固定されている。 Next, the internal structure of the food cutting device will be described in detail. 1 to 4, the food cutting device connects the base 1, the left and right side plates 4 that are coupled to the left and right ends of the base 1 and rise in the vertical direction in parallel to each other, and the rear ends of the side plates 4. A back plate 20 is provided, and the base 1, the left and right side plates 4, and the back plate 20 form a skeleton of a food cutting device. The cutting blade fixing frame 2 is disposed in a substantially vertical posture at a position near the front of the apparatus. The cutting blade fixing frame 2 is dropped along a pair of guide rails whose left and right end edges are fixed to the left and right side plates 4 in the vertical direction, and is substantially fixed between the left and right side plates 4 by the guide rails. Has been.
　切断刃固定枠２は、高さが装置の高さよりも僅かに低い四角形の枠形で、切断刃固定枠２構成する上下の桟によって複数の切断刃３の両端部を支持し、複数の切断刃３は互いに平行に配置されている。図示の例では７本の切断刃３が一定間隔で配置されていて、食品１０を８等分するようになっている。各切断刃３は細長い薄板状の部材で、その幅方向が装置の前後方向に向くように、かつ、刃の形成縁が背面側を向くように配置されている。各切断刃３の表面は食品１０に対する滑りをよくするために例えばフッ素樹脂などでコーティングされている。各切断刃３は長さ方向の両端部が切断刃固定枠２の上記上下の桟に固定された両持ち形式であるため、上記のように細長い薄板状の部材であっても、十分大きな機械的強度を保つことができる。 The cutting blade fixing frame 2 has a rectangular frame shape whose height is slightly lower than the height of the apparatus. The cutting blade fixing frame 2 supports both ends of the plurality of cutting blades 3 by upper and lower bars constituting the cutting blade fixing frame 2. The blades 3 are arranged in parallel to each other. In the illustrated example, seven cutting blades 3 are arranged at regular intervals, and the food 10 is divided into eight equal parts. Each cutting blade 3 is a thin and thin plate-like member, and is arranged so that the width direction thereof faces the front-rear direction of the apparatus and the forming edge of the blade faces the back side. The surface of each cutting blade 3 is coated with, for example, a fluororesin in order to improve the sliding with respect to the food 10. Each of the cutting blades 3 is a double-supported type in which both end portions in the length direction are fixed to the upper and lower crosspieces of the cutting blade fixing frame 2, so that even a long thin plate-like member as described above has a sufficiently large machine Strength can be maintained.
　前記食品載置台５は、図３、図１７に示すように、上側のほぼ半分の側面形状がＬ字形に形成されることにより、Ｌ字の水平辺と垂直辺からなる角隅部に切断前の食品１０を載置することができるようになっている。より具体的には、上記Ｌ字の水平方向に延びる部分が食品１０の底面受け５１、上記Ｌ字の垂直方向に延びる部分が食品１０の背面受け５２となっている。 As shown in FIGS. 3 and 17, the food mounting table 5 is formed in an L-shaped upper half of the side surface before being cut into corners formed by horizontal and vertical sides of the L shape. The food 10 can be placed. More specifically, the L-shaped portion extending in the horizontal direction is the bottom surface receiver 51 of the food 10, and the L-shaped portion extending in the vertical direction is the back surface receiver 52 of the food 10.
　図１６、図１７、図１８に示すように、上記底面受け５１は、左右両端部が前方に向かって延び出た突出部５９となっていて、これらの突出部５９に挟まれた中央部の前端面は上記突出部５９の前端面から後退している。上記左右の突出部５９と上記中央部との間には、前端面から後方に向かってスリット７９が形成されている。上記左右の各突出部５９を左右方向に貫いて水平軸５５が設けられ、各水平軸５５によって位置規制部材７が垂直面内において回転可能に支持されている。各位置規制部材７は、上記各突出部５９の外側面側に位置する外側レバー７０１と、内側面側に位置する内側レバー７０２を対にして有している。 As shown in FIGS. 16, 17, and 18, the bottom surface receiver 51 is a protruding portion 59 with both left and right ends extending forward, and a central portion sandwiched between these protruding portions 59. The front end surface is set back from the front end surface of the protrusion 59. A slit 79 is formed between the left and right protruding portions 59 and the central portion from the front end surface to the rear. A horizontal shaft 55 is provided through the left and right projecting portions 59 in the left-right direction, and the position regulating member 7 is rotatably supported by the horizontal shaft 55 in a vertical plane. Each position regulating member 7 has an outer lever 701 positioned on the outer surface side of each projection 59 and an inner lever 702 positioned on the inner surface side.
　対をなす外側レバー７０１と内側レバー７０２はそれぞれの前端部が軸７４で連結されることにより平面形状がＵ字状に一体化され、さらに、上記水平軸５５で連結されている。こうして、各位置規制部材７は、上記各突出部５９の内外両側において水平軸５５を中心に回転可能に支持されている。上記各軸７４は上記各突出部５９の前方に位置し、各軸７４の外周には円筒形状の錘７５が取り付けられている。内側レバー７０２の水平軸５５より後ろ側の大半は上記スリット７９内にあり、このスリット７９内において水平軸５５を中心に回転可能となっている。 The pair of outer lever 701 and inner lever 702 are integrated in a U shape by connecting their front end portions with a shaft 74, and are further connected with the horizontal shaft 55. Thus, each position restricting member 7 is supported so as to be rotatable about the horizontal shaft 55 on both the inside and outside of each projection 59. Each shaft 74 is positioned in front of each projection 59, and a cylindrical weight 75 is attached to the outer periphery of each shaft 74. Most of the rear side of the inner lever 702 from the horizontal shaft 55 is in the slit 79, and the slit 79 can be rotated around the horizontal shaft 55.
　各外側レバー７０１は後方に延びた腕７１と前方に延びた腕７２と下方に延びた突起７３を有する３腕状のレバーで、前方に延びた腕７２の前端部と内側レバー７０２の前端部が上記軸７４で連結されている。図１８に示すように、各内側レバー７０２は、水平軸５５よりも後ろ側に三つの突起７６，７７，７８を、前側から後ろ側に向かってこの順に有している。位置規制部材７は水平軸５５を中心とした前後の重量バランスによって姿勢が変わるようになっていて、外力が加わらない自然状態では、図３、図１９等において反時計回りに回転付勢され、上記突起７３が食品載置台５の側部に側方に突出して形成された突出部５０の前端面６９に当接することにより上記付勢力による回転が規制されるようになっている。図１９は、位置規制部材７が上記のような外力が加わらない自然状態で、付勢力による回転が規制されている状態を示している。位置規制部材７が図１９に示すような自然状態での姿勢をとっているときは、三つの突起７６，７７，７８が全て食品載置台５の底面受け５１の上面よりも上方に進出する。 Each outer lever 701 is a three-armed lever having an arm 71 extending rearward, an arm 72 extending forward, and a protrusion 73 extending downward. The front end of the arm 72 extending forward and the front end of the inner lever 702 Are connected by the shaft 74. As shown in FIG. 18, each inner lever 702 has three protrusions 76, 77, 78 on the rear side of the horizontal shaft 55 in this order from the front side to the rear side. The posture of the position restricting member 7 changes depending on the weight balance around the horizontal axis 55, and in a natural state where no external force is applied, the position restricting member 7 is urged to rotate counterclockwise in FIGS. The protrusion 73 is in contact with a front end surface 69 of a protruding portion 50 formed to protrude sideways on the side of the food placing table 5, so that rotation by the biasing force is restricted. FIG. 19 shows a state where the position regulating member 7 is in a natural state where the external force is not applied as described above and the rotation by the urging force is restricted. When the position restricting member 7 is in the natural state as shown in FIG. 19, the three protrusions 76, 77, 78 all advance above the upper surface of the bottom surface receiver 51 of the food placing table 5.
　三つの突起７６，７７，７８は、食品載置台５に載置される食品１０の前方に進出することにより、食品１０が底面受け５１上を前方に向かって移動することを阻止して食品１０を所定の位置に位置規制するストッパの役目をする。食品１０の横断面の大きさは大、中、小の３段階に分けることができる。図１９は小サイズの食品１０が底面受け５１と背面受け５２で形成される角隅部に載置されることにより、小サイズの食品１０が内側レバー７０２の後端よりも後方にある状態を示している。この状他では、位置規制部材７が上記のような重量バランスによる付勢力で回転し、かつ前記突起７３が食品載置台５の側部に形成された突出部５０の前端面６９に当接して回転が阻止された姿勢をとっている。この回転姿勢では三つの突起７６，７７，７８のうち最も後ろの突起７８が食品１０の前方にあって食品１０の移動を阻止している。 The three protrusions 76, 77, 78 prevent the food 10 from moving forward on the bottom support 51 by moving forward in front of the food 10 placed on the food placing table 5. It serves as a stopper that restricts the position of the lens to a predetermined position. The size of the cross section of the food 10 can be divided into three levels: large, medium, and small. FIG. 19 shows a state in which the small-sized food 10 is placed behind the rear end of the inner lever 702 by placing the small-sized food 10 on the corners formed by the bottom surface receiver 51 and the back surface receiver 52. Show. In this state and the like, the position restricting member 7 is rotated by the urging force due to the weight balance as described above, and the protrusion 73 is in contact with the front end surface 69 of the protruding portion 50 formed on the side portion of the food placing table 5. The posture is prevented from rotating. In this rotational posture, the rearmost projection 78 of the three projections 76, 77, 78 is in front of the food 10 and prevents the food 10 from moving.
　中サイズの食品が食品載置台５に載置されると、各内側レバー７０２の突起７７と突起７８の間の窪みに食品の前端下縁部が当たり、食品の重みで位置規制部材７を図１９に示す態様から時計回りに回転させ、突起７７で食品の移動を阻止する。図１７、図１８は大サイズの食品１０が食品載置台５に載置された状態を示している。大サイズの食品１０が食品載置台５に載置されると、各内側レバー７０２の突起７６と突起７７の間の窪みに食品１０の前端下縁部が当たり、食品１０の重みで位置規制部材７を図１７、図１８においてさらに時計回りに回転させ、突起７６で食品１０の移動を阻止するようになっている。上記のように中サイズまたは大サイズの食品１０の重みによって各位置規制部材７が回転するとき、その内側レバー７０２の後半部分が、弧を描きながら前記スリット７９内を移動する。 When the medium-sized food is placed on the food placing table 5, the lower edge of the front end of the food hits the recess between the protrusions 77 and 78 of each inner lever 702, and the position regulating member 7 is illustrated by the weight of the food. 19 is rotated clockwise from the mode shown in FIG. 17 and 18 show a state where the large-sized food 10 is placed on the food placing table 5. When the large-sized food 10 is placed on the food placing table 5, the lower edge of the front end of the food 10 hits a recess between the protrusion 76 and the protrusion 77 of each inner lever 702, and the position regulating member is weighted with the food 10. 17 and 18 are further rotated clockwise, and the protrusion 76 prevents the food 10 from moving. As described above, when each position restricting member 7 is rotated by the weight of the medium-sized or large-sized food 10, the latter half of the inner lever 702 moves in the slit 79 while drawing an arc.
　各位置規制部材７の外側レバー７０１の腕７１は、食品１０が切断刃３で切断されたあと位置規制部材７による食品１０の位置規制を解除し、切断された食品１０を食品載置台５から放出するために設けられている。上記腕７１は、左右の側板４に固定されているストッパ１１と共働して位置規制部材７を前記付勢力に抗して回転させ、前記突起７６，７７，７８による食品１０の位置規制を解除し、切断された食品１０を放出するようになっている。この放出動作については本実施例の動作の説明で詳細に説明する。 The arm 71 of the outer lever 701 of each position restricting member 7 releases the position restriction of the food 10 by the position restricting member 7 after the food 10 is cut by the cutting blade 3, and the cut food 10 is removed from the food placing table 5. It is provided for discharge. The arm 71 cooperates with the stopper 11 fixed to the left and right side plates 4 to rotate the position restricting member 7 against the urging force, thereby restricting the position of the food 10 by the protrusions 76, 77, 78. It cancels | releases and the cut | disconnected foodstuff 10 is discharge | released. This discharge operation will be described in detail in the description of the operation of this embodiment.
　食品載置台５に載置されている食品１０を前記切断刃３で切断するために、食品載置台５には切断刃３が進入することができるスリット５８が形成されている。スリット５８は切断刃固定枠２に固定される切断刃３の数および設置位置に対応した数と位置に設けられる。図示の実施例では、食品１０の分割数を４個、６個、８個のいずれかを選択することができるように、左右方向の中央のスリットを中心にして上記の分割数にそれぞれ対応した位置にスリット５８が形成されている。各スリット５８は、切断刃３を迎え入れて食品１０を確実に切断することができるように、図１６に示すように、前記底面受け５１および背面受け５２を含む広い範囲にまたがって深く切り込まれている。 In order to cut the food 10 placed on the food placing table 5 with the cutting blade 3, the food placing table 5 is formed with a slit 58 through which the cutting blade 3 can enter. The slits 58 are provided at the number and position corresponding to the number and installation positions of the cutting blades 3 fixed to the cutting blade fixing frame 2. In the illustrated embodiment, the number of divisions of the food 10 can be selected from 4, 6, and 8, respectively, so that each of the divisions corresponds to the above-mentioned division number around the central slit in the left-right direction. A slit 58 is formed at the position. As shown in FIG. 16, each slit 58 is deeply cut across a wide range including the bottom face receiver 51 and the back face receiver 52 so that the food 10 can be reliably cut by receiving the cutting blade 3. ing.
　食品載置台５は、図示の実施例ではフッ素系の樹脂を切削加工して製作されている。したがって、上記のように複数のかつ深いスリット５８を設けると強度が低下するので、スリット形成部分を避けた櫛歯形の金属製補強部材（図示されず）を固着して強度を補っている。なお、食品載置台５は、これを板金加工によって作成してもよい。 The food mounting table 5 is manufactured by cutting a fluorine-based resin in the illustrated embodiment. Accordingly, since the strength is reduced when a plurality of deep slits 58 are provided as described above, a comb-shaped metal reinforcing member (not shown) that avoids the slit forming portion is fixed to supplement the strength. In addition, you may produce the food mounting base 5 by sheet metal processing.
　食品載置台５の底面受け５１には、スリット５８と平行に複数の溝５７が刻まれている。上記溝５７は、後で詳細に説明する受け部材８の突起８５と共働して、切断された食品１０を受け部材８に円滑に受け渡すために設けられている。上記溝５７は、食品１０の前記何れの分割数にも対応できる位置に形成されていて、スリット５８の縁部に刻まれているものもあり、スリット５８相互間に刻まれているものもある。 A plurality of grooves 57 are engraved on the bottom surface receiver 51 of the food mounting table 5 in parallel with the slits 58. The groove 57 is provided in order to smoothly deliver the cut food 10 to the receiving member 8 in cooperation with the projection 85 of the receiving member 8 described in detail later. The said groove | channel 57 is formed in the position which can respond | correspond to any said division | segmentation number of the foodstuff 10, and what is carved in the edge part of the slit 58, and there are some which are carved between the slits 58. .
　図３、図１６などに示すように、食品載置台５には、載置される食品１０の長さ方向両端位置を規制する規制板５６が背面受け５２の両端部に設けられている。規制板５６は金属板を折り曲げて成形したもので、その基部で背面受け５２を上側から挟み込むように装着し、固定ねじ６０で背面受け５２に固定するようになっている。固定ねじ６０を緩めると規制板５６の位置を上記背面受け５２に沿ってずらすことができる。食品１０が例えば海苔巻き寿司であるとすれば、海苔の寸法は２０５ｍｍ×１８５ｍｍに規格化されているため、海苔を横長にして巻くか、縦長にして巻くかによって切断前の海苔巻き寿司の長さが変わる。そこで、固定ねじ６０を緩めて一対の規制板５６の間隔を海苔巻き寿司の長さに合致するように調整し、固定ねじ６０を締めつけて規制板５６を固定する。 As shown in FIG. 3, FIG. 16, and the like, the food placing table 5 is provided with restricting plates 56 that restrict both end positions of the food 10 to be placed in the length direction at both ends of the back support 52. The restricting plate 56 is formed by bending a metal plate, and is mounted so that the back support 52 is sandwiched from above at the base, and fixed to the back support 52 with a fixing screw 60. When the fixing screw 60 is loosened, the position of the restricting plate 56 can be shifted along the back support 52. If the food 10 is, for example, a seaweed sushi roll, the size of the seaweed is standardized to 205 mm x 185 mm, so the length of the seaweed roll sushi before cutting depends on whether the seaweed is rolled horizontally or vertically. Changes. Therefore, the fixing screw 60 is loosened to adjust the distance between the pair of regulating plates 56 so as to match the length of the seaweed roll sushi, and the regulating screw 56 is tightened to fix the regulating plate 56.
　次に、前記駆動機構６について詳細に説明する。図２ないし図４において、左の側板４の内面側には駆動源としてのモータ６１が固定され、モータ６１の出力軸に固着されたギヤ６２は、軸６４に固着されたギヤ６３と噛み合っている。軸６４は左右の側板４にまたがって回転可能に支持されていて、左右の側板４を貫通した軸６４の両端部にはそれぞれ駆動アーム６５が固着されている。モータ６１の回転駆動力は、ギヤ６２，６３を介して軸６４に伝達され、軸６４と一体の各駆動アーム６５を各側板４の外側面と平行をなす面内において回転駆動するように構成されている。各駆動アーム６５は軸６４の回転中心を通る直線に沿って長孔６６を有していて、この長孔６６に、食品載置台５の前記二つのピン５３，５４のうち前側のピン５３が嵌っている。したがって、各駆動アーム６５が軸６４とともに軸６４を中心に回転駆動されると、長孔６６を画する側面でピン５３が押され、各駆動アーム６５の回転に伴って食品載置台５も移動させられるようになっている。 Next, the drive mechanism 6 will be described in detail. 2 to 4, a motor 61 as a drive source is fixed to the inner surface side of the left side plate 4, and the gear 62 fixed to the output shaft of the motor 61 is engaged with the gear 63 fixed to the shaft 64. Yes. The shaft 64 is rotatably supported across the left and right side plates 4, and drive arms 65 are fixed to both ends of the shaft 64 that penetrates the left and right side plates 4. The rotational driving force of the motor 61 is transmitted to the shaft 64 through the gears 62 and 63, and is configured to rotationally drive each driving arm 65 integral with the shaft 64 in a plane parallel to the outer surface of each side plate 4. Has been. Each drive arm 65 has a long hole 66 along a straight line passing through the rotation center of the shaft 64, and the front pin 53 of the two pins 53, 54 of the food mounting table 5 is inserted into the long hole 66. It fits. Therefore, when each drive arm 65 is driven to rotate about the shaft 64 together with the shaft 64, the pin 53 is pushed on the side surface that defines the long hole 66, and the food mounting table 5 moves as the drive arm 65 rotates. It is supposed to be made.
　食品載置台５の左右両側にある上記二つのピン５３，５４はカム溝９１に嵌っていてカムフォロワとして機能している。食品載置台５の高さ位置および姿勢は二つのピン５３，５４の高さ位置および相対的な高さの違いによって決まり、二つのピン５３，５４の相対的な高さ位置関係はカム溝９１の形によって決まる。図示の例では、カム溝９１はカム板９に形成されていて、カム板９が側板４に固定されている。
　カム溝９１は、これを側板４に形成してカム板９を省略してもよい。 The two pins 53 and 54 on the left and right sides of the food placing table 5 are fitted in the cam groove 91 and function as a cam follower. The height position and posture of the food mounting table 5 are determined by the difference in height position and relative height between the two pins 53 and 54, and the relative height positional relationship between the two pins 53 and 54 is determined by the cam groove 91. It depends on the shape of In the illustrated example, the cam groove 91 is formed in the cam plate 9, and the cam plate 9 is fixed to the side plate 4.
The cam groove 91 may be formed in the side plate 4 and the cam plate 9 may be omitted.
　カム溝９１は、図１１、図１２などに示すように、食品１０が切断刃３に接触し始めると、食品１０に対する切断刃３の進入角度が連続的に変化するように食品載置台１０の姿勢を連続して変化させる円弧部９３と、食品１０に切断刃３が侵入した後は食品載置台５の姿勢を一定に保って食品載置台５を直線的に移動させる直線部９４を有してなる。上記円弧部９３を上記二つのピン５３，５４が通るとき、食品１０に対する切断刃３の進入角度の連続的な変化が、食品１０の切断刃３に対する相対速度を早めるように、上記二つのピン５３，５４が摺接する上記円弧部９３の面（図１１、図１２において下側の面）が凸面に形成されている。 As shown in FIGS. 11, 12, and the like, the cam groove 91 is configured so that when the food 10 starts to contact the cutting blade 3, the entrance angle of the cutting blade 3 to the food 10 continuously changes. An arc portion 93 that continuously changes the posture, and a linear portion 94 that linearly moves the food placing table 5 while keeping the posture of the food placing table 5 constant after the cutting blade 3 enters the food 10. It becomes. When the two pins 53 and 54 pass through the arc portion 93, the two pins 53 and 54 continuously change the approach angle of the cutting blade 3 with respect to the food 10 to increase the relative speed of the food 10 with respect to the cutting blade 3. The surface of the arc portion 93 (the lower surface in FIGS. 11 and 12) with which 53 and 54 are in sliding contact is formed as a convex surface.
　切断刃３はほぼ垂直方向の姿勢を保って固定されているのに対し、カム溝９１の上記直線部９４は適宜の角度傾いていて、直線部９４に沿って食品載置台５が上から斜め下に向かって移動するとき、食品載置台５はお辞儀をしたように傾斜した姿勢すなわち前傾姿勢をとっている。この傾斜した姿勢をとっている食品載置台５に保持された食品１０に切断刃３が上記傾斜角度に対応した角度で接しながら食い込むようになっている。 The cutting blade 3 is fixed while maintaining a substantially vertical posture, whereas the linear portion 94 of the cam groove 91 is inclined at an appropriate angle, and the food placing table 5 is inclined from above along the linear portion 94. When moving downward, the food placing table 5 takes a tilted posture, that is, a forward tilted posture as if bowed. The cutting blade 3 bites into the food 10 held on the food placing table 5 taking this inclined posture while contacting the food 10 at an angle corresponding to the inclination angle.
　カム溝９１は、上端部が上記円弧部９３に続く円弧部９２になっている。この円弧部９２に上記二つのピン５３，５４があるとき、図３、図４に示すように食品載置台５は最も上位にあり、かつ、底面受け５１が水平の姿勢よりも僅かに奥側が下がった姿勢になって、食品１０の受け入れ姿勢をとるようになっている。駆動機構６は、モータ６１からカム溝９１に至る構成部分を含んでいる。 The upper end of the cam groove 91 is an arc 92 that follows the arc 93. When the arc portion 92 has the two pins 53 and 54, as shown in FIGS. 3 and 4, the food placing table 5 is at the highest position, and the bottom support 51 is slightly behind the horizontal posture. The posture is lowered and the food 10 is accepted. The drive mechanism 6 includes components from the motor 61 to the cam groove 91.
　ここで、上記二つのピン５３，５４がカム溝９１に沿って移動するときの食品載置台５の姿勢および位置の変化について説明しておく。上記のように食品１０の受け入れ姿勢をとっている食品載置台５に食品１０を載置し、駆動機構６を動作させると、二つのピン５３，５４がカム溝９１の円弧部９２から円弧部９３に移動し、さらに直線部９４に移動する。ピン５３，５４が上記円弧部９３を通るとき、ピン５３の高さ位置がピン５４の高さ位置よりも徐々に低くなり、食品載置台５の姿勢が前傾姿勢となるとともに前傾角度が徐々に大きくなる。食品載置台５が姿勢を変化させているとき、食品載置台５に載置されている食品１０が切断刃３に接触し始めるように、切断刃３、食品載置台５、ピン５３，５４、カム溝９１相互の位置関係が設定されている。ピン５３，５４は、上記円弧部９３を通過した後はカム溝９１の直線部９４に導かれ、食品載置台５は上記の前傾姿勢のままで前述のように上から斜め下に向かって直線状に移動し、切断刃３で食品が切断される。切断された食品１０は次に説明する受け部材８で受け取られ、続いて駆動機構６が逆向きに動作して食品載置台５を原位置に復帰させる。 Here, changes in the posture and position of the food placing table 5 when the two pins 53 and 54 move along the cam groove 91 will be described. When the food 10 is placed on the food placing table 5 taking the food 10 as described above and the drive mechanism 6 is operated, the two pins 53 and 54 are moved from the arc portion 92 of the cam groove 91 to the arc portion. 93, and further moves to the straight line portion 94. When the pins 53 and 54 pass through the circular arc portion 93, the height position of the pin 53 gradually becomes lower than the height position of the pin 54, the posture of the food placing table 5 becomes the forward tilt posture, and the forward tilt angle is Gradually grows. When the food placing table 5 is changing its posture, the cutting blade 3, the food placing table 5, the pins 53 and 54, so that the food 10 placed on the food placing table 5 starts to contact the cutting blade 3. The positional relationship between the cam grooves 91 is set. After passing through the circular arc part 93, the pins 53 and 54 are guided to the straight part 94 of the cam groove 91, and the food placing table 5 remains obliquely downward from the top as described above while keeping the forward tilting posture. It moves linearly and the food is cut by the cutting blade 3. The cut food 10 is received by the receiving member 8 described below, and then the drive mechanism 6 operates in the reverse direction to return the food placing table 5 to the original position.
　次に、前記受け部材８を含む切断後の食品１０の受け取り部の構成について詳細に説明する。図２、図３、図４などに示すように、装置の前側下部に設けられている切断後の食品１０の受け取り部の主な構成部材は受け部材８である。受け部材８は、斜め下に向かって滑り落ちてくる切断後の食品１０を受け取る傾斜ガイド部８１と、この傾斜ガイド部８１の下端縁部に続いてほぼ直角に延び出て上記食品１０の滑落を受け止める受け取り部８２を有している。また、受け部材８は、傾斜ガイド部８１の下面側にスライド部８３を一体に有していて、スライド部８３は側板４の内面側に固定された溝形のガイドレール１２にスライド可能に嵌められている。上記傾斜ガイド部８１は、前述のように傾斜した食品載置台５の傾斜角度に近い角度で傾斜しており、この傾斜角度と同じ角度でガイドレール１２が固定されている。 Next, the configuration of the receiving part of the cut food 10 including the receiving member 8 will be described in detail. As shown in FIGS. 2, 3, 4, and the like, a main component member of the receiving portion of the cut food 10 provided in the lower front side of the apparatus is a receiving member 8. The receiving member 8 has an inclined guide portion 81 that receives the cut food 10 that slides down obliquely downward, and extends substantially perpendicularly to the lower end edge of the inclined guide portion 81 to slide down the food 10. It has the receiving part 82 which receives. The receiving member 8 integrally has a slide portion 83 on the lower surface side of the inclined guide portion 81, and the slide portion 83 is slidably fitted to a groove-shaped guide rail 12 fixed to the inner surface side of the side plate 4. It has been. The inclined guide portion 81 is inclined at an angle close to the inclination angle of the food mounting table 5 inclined as described above, and the guide rail 12 is fixed at the same angle as this inclination angle.
　図２、図３に示すように、上記傾斜ガイド部８１の後端縁には、前記食品載置台５の底面受け５１に形成されている溝５７（図１６参照）と協働して切断後の食品１０を円滑に受け部材８に放出させる突起８５が、上記溝５７に対応して複数形成されている。受け部材８は、図示されないばねなどの付勢部材により、図２、図３、図４などに示すように、斜め上方に移動するように付勢されている。付勢力によって移動した受け部材８は適宜の規制手段により切断後の食品１０の受け取り位置で移動が規制されている。上記付勢力は、受け部材８自体の荷重に打ち勝って斜め上方に移動することができる程度の比較的弱い付勢力であって、受け部材８が食品１０を受け取ったとき受け部材８に加わる荷重が勝り、付勢力に抗して受け部材８が斜め下方に移動するようになっている。したがって、受け部材８から食品１０を取り出すと、受け部材８は付勢力で原位置に戻る。 As shown in FIGS. 2 and 3, the rear end edge of the inclined guide portion 81 is cut in cooperation with a groove 57 (see FIG. 16) formed in the bottom surface receiver 51 of the food placing table 5. A plurality of projections 85 for smoothly releasing the food 10 to the receiving member 8 are formed corresponding to the grooves 57. The receiving member 8 is urged to move obliquely upward by an urging member such as a spring (not shown) as shown in FIGS. The movement of the receiving member 8 moved by the urging force is restricted at the receiving position of the food 10 after cutting by an appropriate restricting means. The urging force is a relatively weak urging force that can overcome the load of the receiving member 8 itself and move obliquely upward, and the load applied to the receiving member 8 when the receiving member 8 receives the food 10. The receiving member 8 moves diagonally downward against the urging force. Therefore, when the food 10 is taken out from the receiving member 8, the receiving member 8 returns to the original position by the urging force.
　各側板４の内面側には、受け部材８に近接してその上方にストッパ１１が固定されている。ストッパ１１は、食品載置台５とともに移動してきた位置規制部材７の後方に延びた腕７１の移動軌跡内にあり、食品載置台５がカム溝９１に沿って下降し、載置されている食品１０が切断刃３で切断された直後、上記腕７１がストッパ１１の後面側に摺接するようになっている。位置規制部材７は前述のような重量配分によって、水平軸５５を中心として回転付勢され、付勢力による回転が規制された姿勢をとるが、腕７１がストッパ１１に当たることにより、図１２、図１３に示すように位置規制部材７は強制的に時計方向に回転させられ、前記突起７６，７７，７８が食品載置台５の底面受け５１の上面より下に沈むようになっている。 A stopper 11 is fixed on the inner surface side of each side plate 4 close to the receiving member 8 and above it. The stopper 11 is in the movement trajectory of the arm 71 extending rearward of the position regulating member 7 that has moved together with the food placing table 5, and the food placing table 5 descends along the cam groove 91 and is placed on the food. Immediately after 10 is cut by the cutting blade 3, the arm 71 comes into sliding contact with the rear surface side of the stopper 11. The position restricting member 7 is urged to rotate about the horizontal shaft 55 by the weight distribution as described above, and takes a posture in which the rotation by the urging force is restricted. However, when the arm 71 hits the stopper 11, FIG. As shown in FIG. 13, the position restricting member 7 is forcibly rotated clockwise so that the protrusions 76, 77, 78 sink below the upper surface of the bottom surface receiver 51 of the food placing table 5.
　次に、以上のように構成されている実施例の動作を説明する。図１乃至図４は動作開始前の初期状態を示しており、食品載置台５は二つのピン５３，５４がカム溝９１の上側終端部の円弧部９２にあって切断前の食品１０の載置姿勢をとっている。この態様の食品載置台５に食品１０を載置する。載置される食品１０が小サイズの食品であれば、食品載置台５は上記載置姿勢のままで食品１０を受け入れ、図１９に示すように位置規制部材７の突起７８が食品１０の前方に進出している。既に述べたように、載置される食品１０が中サイズであれば位置規制部材７が食品１０の荷重により位置規制部材７自体の重量バランスに抗して回転し、突起７７が食品１０の前方に進出する。同様に、載置される食品１０が大サイズであれば、図１８に示すように位置規制部材７がそれ自体の重量バランスに抗して回転し、突起７６が食品１０の前方に進出する。 Next, the operation of the embodiment configured as described above will be described. 1 to 4 show an initial state before the operation is started, and the food placing table 5 has two pins 53 and 54 in the arc portion 92 of the upper end portion of the cam groove 91 and the food 10 before cutting is placed thereon. I take a posture. The food 10 is placed on the food placing table 5 of this aspect. If the food 10 to be placed is a small-sized food, the food placing table 5 accepts the food 10 in the above-described posture, and the projection 78 of the position regulating member 7 is located in front of the food 10 as shown in FIG. Have advanced to. As already described, if the food 10 to be placed is a medium size, the position restricting member 7 rotates against the weight balance of the position restricting member 7 itself due to the load of the food 10, and the protrusion 77 moves forward of the food 10. To advance to. Similarly, if the food 10 to be placed is a large size, the position restricting member 7 rotates against its own weight balance as shown in FIG. 18 and the protrusion 76 advances to the front of the food 10.
　次に、スタートボタンを操作すると、モータ６１が起動され、駆動機構６が動作を開始する。ギヤ列６１，６２、軸６４を経て駆動機構６の駆動アーム６５が図３において反時計方向に回転駆動され、その長孔６６に嵌っている食品載置台５のピン５３がカム溝９１に沿って移動させられる。ピン５３とともにピン５４もカム溝９１に沿って移動し、食品載置台５の高さ位置と姿勢が二つのピン５３、５４の高さ位置および相互の高さ位置の違いによって定まる。ピン５３、５４がカム溝９１の円弧部９３の位置にさしかかると、ピン５３の高さ位置がピン５４の高さ位置に対して連続的に低くなり、もって、食品載置台５が前傾姿勢をとるとともに前傾姿勢が徐々に深くなる。このように、食品載置台５が前傾姿勢をとり始める位置は、食品１０が切断刃３に接触し始めるときである。食品１０と切断刃３の接触開始当初は、食品１０に対する切断刃３の進入角度を連続的に変化させて切断刃３と食品１０の相対速度を速めるようになっている。図５、図１０はこのときの動作態様示している。こうして切断開始当初の食品１０への切断刃３の進入を容易にし、食品１０の切断時に食品１０に加わる圧力を小さくして食品１０の変形を低減することができるように工夫されている。 Next, when the start button is operated, the motor 61 is activated and the drive mechanism 6 starts operating. The drive arm 65 of the drive mechanism 6 is driven to rotate counterclockwise in FIG. 3 via the gear trains 61 and 62 and the shaft 64, and the pin 53 of the food placing table 5 fitted in the long hole 66 extends along the cam groove 91. Moved. The pin 54 moves together with the pin 53 along the cam groove 91, and the height position and posture of the food placing table 5 are determined by the difference in height position between the two pins 53 and 54 and the mutual height position. When the pins 53 and 54 reach the position of the arc portion 93 of the cam groove 91, the height position of the pin 53 is continuously lowered with respect to the height position of the pin 54, so that the food placing table 5 is tilted forward. The forward leaning posture gradually deepens. As described above, the position at which the food placing table 5 starts to take the forward leaning posture is when the food 10 starts to contact the cutting blade 3. At the beginning of contact between the food 10 and the cutting blade 3, the relative angle between the cutting blade 3 and the food 10 is increased by continuously changing the approach angle of the cutting blade 3 with respect to the food 10. 5 and 10 show the operation mode at this time. Thus, the cutting blade 3 can be easily entered into the food 10 at the beginning of cutting, and the pressure applied to the food 10 when the food 10 is cut can be reduced to reduce the deformation of the food 10.
　食品載置台５のピン５３、５４がカム溝９１の直線部９４に至ると、食品載置台５は最大の傾斜角度を保ったまま上記直線部９４に沿って斜め下方に移動する。この間、食品載置台５に載置されている食品１０は、その前方に進出している突起７６，７７，７８のうちの一つで食品載置台５から滑落することが阻止されている。このようにして、垂直方向に両持ち状に固定された切断刃３に対し、食品載置台５とともに食品１０が斜め下方に相対移動することにより、切断刃３が一定の相対速度によって食い込み、食品１０が輪切り状に切断される。図１１はこの動作態様を示している。 When the pins 53 and 54 of the food placing table 5 reach the straight portion 94 of the cam groove 91, the food placing table 5 moves obliquely downward along the straight portion 94 while maintaining the maximum inclination angle. During this time, the food 10 placed on the food placing table 5 is prevented from sliding off from the food placing table 5 by one of the protrusions 76, 77, 78 that have advanced to the front thereof. In this way, the food blade 10 moves obliquely downward together with the food mounting table 5 with respect to the cutting blade 3 that is fixed in a doubly supported manner in the vertical direction, so that the cutting blade 3 bites in at a constant relative speed. 10 is cut into a ring shape. FIG. 11 shows this mode of operation.
　図６、図１２は、上記ピン５３、５４がカム溝９１の直線部９４に沿って斜め下方に下降し、食品載置台５が食品１０の切断動作の終端近くに至った状態を示している。この状態では位置規制部材７の腕７１がストッパ１１の背面に接触し始めている。食品載置台５がさらに下降すると、図７、図１３に示すように、食品１０が切断刃３の位置を通り過ぎて食品１０が切断される。また、位置規制部材７はその腕７１がストッパ１１に押されて重量バランスに抗して時計方向に回転させられ、前記突起７６，７７，７８の全てが食品１０の前方から下方に退避する。こうして突起７６，７７，７８による食品１０の位置規制態様が解除され、食品１０は食品載置台５の底面受け５１から放出される。食品１０は食品載置台５の前傾姿勢に沿って受け部材８の傾斜ガイド部８１に滑り落ち、受け取り部８２で受け止められる。 6 and 12 show a state in which the pins 53 and 54 are lowered obliquely downward along the straight line portion 94 of the cam groove 91 and the food placing table 5 has come close to the end of the cutting operation of the food 10. . In this state, the arm 71 of the position regulating member 7 starts to contact the back surface of the stopper 11. When the food placing table 5 is further lowered, the food 10 passes through the position of the cutting blade 3 and is cut as shown in FIGS. Further, the arm 71 of the position restricting member 7 is pushed by the stopper 11 and is rotated clockwise against the weight balance, and all the protrusions 76, 77, 78 are retracted downward from the front of the food 10. Thus, the position regulation mode of the food 10 by the protrusions 76, 77, 78 is released, and the food 10 is released from the bottom surface receiver 51 of the food placing table 5. The food 10 slides down on the inclined guide portion 81 of the receiving member 8 along the forward inclined posture of the food placing table 5 and is received by the receiving portion 82.
　食品１０を受け取った受け部材８には食品１０の荷重がかかり、この荷重が受け部材８の前記付勢力に勝るため、受け部材８は食品１０を保持したまま斜め下方にスライドする。こうして切断後の食品１０は、食品載置台５の移動軌跡外に下降して取り出し口に至り、切断後の食品１０を取り出すことができる。上記傾斜ガイド部８１および受け取り部８２の両側部には食品１０の両側を規制する板などは設けられておらず、上記両側部が開放されている。切断後の食品１０の取り出し作業が容易になるように配慮したためである。 The receiving member 8 that receives the food 10 is loaded with the food 10, and this load overcomes the urging force of the receiving member 8, so the receiving member 8 slides diagonally downward while holding the food 10. Thus, the cut food 10 descends out of the movement trajectory of the food placing table 5 and reaches the takeout port, so that the cut food 10 can be taken out. The both sides of the inclined guide part 81 and the receiving part 82 are not provided with a plate or the like for restricting both sides of the food 10, and the both side parts are open. This is because consideration has been given to facilitate the work of taking out the food 10 after cutting.
　上記のようにして、食品１０が受け部材８に受け渡されることによって、食品載置台５の移動軌跡から食品１０が退避するので、駆動機構６を逆転させることにより、食品載置台５を含む全ての動作部を図２、図３、図４に示すような原位置に復帰させることができる。駆動機構６を逆転させるタイミングは、例えば、受け部材８が斜め下方にスライドしたことを検知したとき、あるいは、受け部材８に食品１０が滑落してきたことを検知したときにするとよい。また、食品載置台５が移動行程の終端まで下降して一定時間経過したら原位置に向かって復帰動作を開始させるように、駆動機構６の制御回路を構成してもよい。このように構成すれば、上記のような検知を行うためのセンサの類を設ける必要はない。 When the food 10 is transferred to the receiving member 8 as described above, the food 10 is retracted from the movement locus of the food mounting table 5, so that all of the food mounting table 5 including the food mounting table 5 can be reversed by reversing the drive mechanism 6. Can be returned to their original positions as shown in FIGS. The timing for reversing the drive mechanism 6 may be, for example, when it is detected that the receiving member 8 has been slid obliquely downward, or when it is detected that the food 10 has been slid down on the receiving member 8. Further, the control circuit of the drive mechanism 6 may be configured so that the return operation is started toward the original position when the food placing table 5 is lowered to the end of the moving stroke and a predetermined time has elapsed. If comprised in this way, it is not necessary to provide the kind of sensor for performing the above detections.
　以上説明した食品切断装置の実施例は、両持ち状に固定した切断刃３に対し、食品１０を載せた食品載置台５を移動させて食品１０を切断するようにした食品切断装置において、食品載置台５を移動させる駆動機構６にカム溝９１を有してなるカム機構を用い、カム溝９１の形状を工夫して、食品１０が切断刃３に接触し始めるとき食品１０に対する切断刃３の進入角度を連続的に変化させて切断刃３と食品１０の相対速度を速めるように構成されている。よって、上記食品切断装置の実施例によれば、切断開始当初の食品１０への切断刃３の進入を容易にすることができ、食品１０の切断時に加わる圧力を小さくして食品１０の変形を低減することができる。 The embodiment of the food cutting apparatus described above is a food cutting apparatus in which the food placing table 5 on which the food 10 is placed is moved relative to the cutting blade 3 fixed in a doubly held manner to cut the food 10. When a cam mechanism having a cam groove 91 is used for the drive mechanism 6 for moving the mounting table 5 and the shape of the cam groove 91 is devised, the cutting blade 3 for the food 10 when the food 10 starts to contact the cutting blade 3. The approach angle is continuously changed to increase the relative speed of the cutting blade 3 and the food 10. Therefore, according to the embodiment of the food cutting device, the cutting blade 3 can easily enter the food 10 at the beginning of cutting, and the deformation applied to the food 10 can be reduced by reducing the pressure applied when the food 10 is cut. Can be reduced.
　切断対象食品が巻き寿司のように柔らかく粘りのあるものの場合、切断刃３に飯粒が付着し、あるいは飯粒が糊状に変化したものが付着することにより、切断後の食品１０が切断刃３に粘着し、受け部材８に受け渡すことができないことがあり得る。そこで図示の実施例では、受け部材８の後ろ側の縁部に複数の突起８５を設け、位置規制部材７の底面受け５１に上記各突起８５が進入する溝５７を設けている。図６、図１２に示すように、食品１０を切断し終わる直前に上記各溝５７に突起８５が進入し始め、食品１０を切断し終わったときは食品１０が突起８５で掬われるようにして受け部材８に受け渡されるように、構成が工夫されている。このような工夫をしておけば、切断刃３に粘着しようとする切断後の食品１０を強制的に引き剥がし、受け部材８に円滑に受け渡すことができる。特に、裏巻きと称して、寿司飯が海苔の外側にあるものを切断する場合に効果的である。 When the food to be cut is soft and sticky like sushi rolls, the rice grains adhere to the cutting blade 3 or the rice grains that have changed into a paste form adhere to the food blade 10 after cutting. It may stick and cannot be delivered to the receiving member 8. Therefore, in the illustrated embodiment, a plurality of protrusions 85 are provided on the rear edge of the receiving member 8, and grooves 57 into which the protrusions 85 enter are provided in the bottom surface receiver 51 of the position regulating member 7. As shown in FIGS. 6 and 12, the protrusions 85 begin to enter the grooves 57 immediately before the food 10 is cut, and when the food 10 is cut, the food 10 is scooped by the protrusions 85. The configuration is devised so as to be delivered to the receiving member 8. If such a contrivance is made, the cut food 10 to be adhered to the cutting blade 3 can be forcibly peeled off and smoothly transferred to the receiving member 8. In particular, this is effective when cutting what is on the outside of the seaweed, called sushi roll.
　上記実施例によればまた、切断後の食品１０が自働的に食品載置台５の移動軌跡から退避するため、スタートボタンを１回操作して食品載置台５を往復動作させるだけでよく、従来のように、切断前の食品をセットしてスタートボタンを押し、切断された食品を取り出した後復帰ボタンを押すというような面倒な操作は不要である。また、例えば、装置の上側の食品供給部に食品をセットしてスタートボタンを操作し、切断された食品を装置の下側で取り出し、次に再び食品供給部に食品をセットしてスタートボタンを操作する、というように操作が簡単になり、切断作業の能率化を図ることができる。 According to the above embodiment, since the cut food 10 is automatically retracted from the movement locus of the food placing table 5, it is only necessary to operate the start button once to reciprocate the food placing table 5. Conventionally, troublesome operations such as setting the food before cutting, pressing the start button, taking out the cut food, and pressing the return button are unnecessary. Also, for example, set food in the food supply section on the upper side of the apparatus and operate the start button, take out the cut food under the apparatus, then set the food again in the food supply section and press the start button. The operation becomes simple such as operating, and the efficiency of the cutting work can be improved.
　図１０乃至図１３からわかるように、一連の切断動作で使用される切断刃３の範囲は、略上側の半分である。そこで、前述のように切断刃固定枠２は左右のガイド溝に落とし込んで固定するように構成し、ある程度稼働させると切断刃固定枠２を上下反転させて固定し、続けて稼働させることができるようになっている。こうすれば、一つの切断刃固定枠２の使用による稼働時間を延ばすことができ、この点からも切断作業の能率化を図ることができる。 As can be seen from FIGS. 10 to 13, the range of the cutting blade 3 used in a series of cutting operations is substantially the upper half. Therefore, as described above, the cutting blade fixing frame 2 is configured to be fixed by dropping into the left and right guide grooves, and when the cutting blade fixing frame 2 is operated to some extent, the cutting blade fixing frame 2 can be fixed upside down and continuously operated. It is like that. If it carries out like this, the working time by use of one cutting blade fixed frame 2 can be extended, and efficiency of cutting work can be aimed at also from this point.
　図示の実施例では、受け部材８が、切断後の食品１０を受け取ることによって下方にスライドする構造になっていたが、切断後の食品１０が受け部材８に沿って滑落するように構成しておけば、受け部材８は固定してもよく、スライドする構造にする必要はない。イメージとしては、図１４に示すような切断後の食品１０を受け取って受け部材８がスライドした態様において、受け部材８の後端を切断刃３の近くまで伸ばし、受け部材８の後端縁部に形成されている複数の突起８５が、食品載置台５の前記溝５７に進入することができるように位置決めして受け部材８を固定した構成にする。 In the illustrated embodiment, the receiving member 8 is configured to slide downward by receiving the cut food product 10, but the cut food product 10 is configured to slide along the receiving member 8. In this case, the receiving member 8 may be fixed and does not need to have a sliding structure. As an image, in a mode in which the receiving member 8 is slid after receiving the cut food 10 as shown in FIG. 14, the rear end of the receiving member 8 extends to the vicinity of the cutting blade 3, and the rear end edge of the receiving member 8 A plurality of protrusions 85 formed in the above are positioned so that they can enter the groove 57 of the food placing table 5 and the receiving member 8 is fixed.
　食品載置台５から受け部材８が食品１０を受け取ったことを確認した後に食品載置台５を復帰動作させるために、受け部材８への食品の滑落経路を左右から挟んで例えば発光部と受光部からなる光センサを配置し、光センサが受け部材８への食品の滑落を検知するようにするとよい。あるいは、駆動機構６による食品載置台５の往動工程終端位置で、一定時間経過後復動動作を開始させるようにしてもよい。かかる構成によれば、上記のようなセンサは不要である。 In order to return the food placing table 5 after confirming that the receiving member 8 has received the food 10 from the food placing table 5, for example, a light emitting part and a light receiving part sandwiching the sliding path of the food to the receiving member 8 from the left and right It is good to arrange | position the optical sensor which consists of these, and an optical sensor detects the sliding of the foodstuff to the receiving member 8. Alternatively, the backward movement operation may be started after a predetermined time has passed at the forward movement process end position of the food placing table 5 by the drive mechanism 6. According to such a configuration, the sensor as described above is unnecessary.
　切断刃３は、刃の部分の形状が直線状のものでも差し支えないが、海苔巻きなどへの刃の食い込みを良好にするために、図２０に示すような波形の刃の形状にするとよい。図２０（ａ）は曲線的な波形の刃の形状とした切断刃３１を示す。図２０（ｂ）は波の山の形が鋭角的に尖った刃形とした切断刃３２を示す。何れの刃においても、波形のピッチを適宜設定することによって、切断対象とする食品の性質に合致した切れ味を得ることができる。 The cutting blade 3 may have a straight blade shape, but it may have a corrugated blade shape as shown in FIG. FIG. 20A shows a cutting blade 31 having a curved wave shape. FIG. 20B shows a cutting blade 32 having a blade shape in which the shape of a wave crest is acutely sharp. In any blade, by setting the corrugated pitch appropriately, a sharpness that matches the properties of the food to be cut can be obtained.
　図３、図４などからわかるように、装置の側面から見た駆動アーム６５は一方側が膨出した形になっているが、軽量化を図って駆動力をなるべく軽減するために、上記膨出部をなくした単純な形にしてもよい。また、位置規制部材７などの可動部材は、肉抜きなどを行うことによって軽量化を図るとよい。 As can be seen from FIGS. 3 and 4, the drive arm 65 as seen from the side of the device is bulged on one side. However, in order to reduce the driving force as much as possible in order to reduce the weight, the above bulge It may be a simple shape with no part. Further, the movable member such as the position restricting member 7 may be reduced in weight by performing thinning or the like.
　図示の実施例では、食品載置台の駆動機構がカムを用いて食品載置台の姿勢と移動軌跡を規制する構成になっていたが、カムを用いることなく、他の機構を用いてもよい。例えば、リンク機構を用いることによって、食品と切断刃の接触開始当初は食品に対する切断刃の進入角度を連続的に変化させて切断刃と食品の相対速度を速めるように構成してもよい。あるいは、一定の姿勢を保って直線移動する支持体に、食品載置台を回転可能に取り付け、上記支持体が移動を開始して対象食品と切断刃が接触を開始した当初、上記食品載置台を回転させ、食品に対する切断刃の進入角度を連続的に変化させるように構成してもよい。 In the illustrated embodiment, the food mounting table drive mechanism uses a cam to regulate the posture and movement trajectory of the food mounting table, but other mechanisms may be used without using the cam. For example, by using a link mechanism, the relative angle between the cutting blade and the food may be increased by continuously changing the approach angle of the cutting blade with respect to the food at the beginning of contact between the food and the cutting blade. Alternatively, the food mounting table is rotatably attached to a support that moves linearly while maintaining a fixed posture, and the food mounting table is initially installed when the support starts moving and the target food and the cutting blade start to contact each other. You may comprise so that it may be rotated and the approach angle of the cutting blade with respect to food may be changed continuously.
　次に、切断後の食品を自然落下させるのではなく、切断後の食品を、所定の姿勢で受け取って下降する構成にして、切断後の食品取り出しの作業性をより一層向上させた食品切断装置の実施例について、図２１乃至図３５を参照しながら説明する。なお、前記第１の実施例の構成部品あるいは構成部分と実質的に同一の構成部品あるいは構成部分には同一の符号を付して、説明を簡略化する。 Next, the food cutting apparatus is configured to further improve the workability of taking out the food after the cutting by adopting a configuration in which the food after the cutting is received and lowered in a predetermined posture instead of naturally dropping the food after the cutting. This embodiment will be described with reference to FIGS. It should be noted that the same reference numerals are given to the substantially same components and components as those of the first embodiment, and the description will be simplified.
　図２１乃至図２３において、符号８は切断後の食品の受け部材、１５は前面パネル、１４は側面カバー、５は食品載置台、１０は食品をそれぞれ示している。食品載置台５に食品１０を載置し、スタートスイッチを押すと、食品載置台５が駆動機構によって装置の前側下部に向かって移動させられ、この移動の途中で食品１０が切断刃によって輪切り状に切断され、上記受け部材８に受け渡されるように構成されている。食品載置台５から受け部材８に受け渡された食品１０は、固定された傾斜案内面８４に案内されて上下動する受け部材８の受け取り部８２で受け取られ、受け部材８が斜め下方にスライドし、食品載置台５は駆動機構によって原位置に復帰するように構成されている。 21 to 23, reference numeral 8 denotes a food receiving member after cutting, 15 denotes a front panel, 14 denotes a side cover, 5 denotes a food placing table, and 10 denotes food. When the food 10 is placed on the food placing table 5 and the start switch is pressed, the food placing table 5 is moved toward the lower front side of the apparatus by the drive mechanism, and the food 10 is cut into a ring shape by a cutting blade during the movement. And is delivered to the receiving member 8. The food 10 delivered from the food mounting table 5 to the receiving member 8 is received by the receiving portion 82 of the receiving member 8 which is guided by the fixed inclined guide surface 84 and moves up and down, and the receiving member 8 slides obliquely downward. The food mounting table 5 is configured to return to the original position by the drive mechanism.
　次に、上記食品切断装置の内部構造を詳細に説明する。図２１乃至図２４において、ベース１と、左右の側板４と、背板とで食品切断装置の骨格を構成している。符号２は切断刃固定枠、３は切断刃を示している。切断刃固定枠２と切断刃３は前記第１の実施例における切断刃固定枠２および切断刃３と同様に構成されて食品切断装置に装着されている。 Next, the internal structure of the food cutting device will be described in detail. 21 to 24, the base 1, the left and right side plates 4, and the back plate constitute a skeleton of the food cutting device. Reference numeral 2 denotes a cutting blade fixing frame, and 3 denotes a cutting blade. The cutting blade fixing frame 2 and the cutting blade 3 are configured in the same manner as the cutting blade fixing frame 2 and the cutting blade 3 in the first embodiment and are attached to the food cutting apparatus.
　前記食品載置台５は、図２４に示すように、上側のほぼ半分の側面形状がＬ字形をしていて、Ｌ字の水平方向に延びる部分が食品１０の底面受け５１、上記Ｌ字の垂直方向に延びる部分が食品１０の背面受け５２となっている。食品載置台５によって受けられる海苔巻きのような食品には幾種類かのサイズがある。第１の実施例と同様に、食品のサイズが異なっても、これに対応してこれを食品載置台５に保持することを可能にした機構が設けられている。 As shown in FIG. 24, the food mounting table 5 has an L-shaped upper half side surface, and the L-shaped portion extending in the horizontal direction has a bottom receiving 51 for the food 10, and the L-shaped vertical. A portion extending in the direction is a back support 52 of the food 10. There are several sizes of foods such as laver rolls received by the food table 5. Similar to the first embodiment, there is provided a mechanism that enables the food placing table 5 to hold the food corresponding to different food sizes.
　図２２、図２３に示すように、食品載置台５には切断刃３が進入することができるスリット５８が切断刃３の数および設置位置に対応した数と位置に設けられている。各スリット５８は、切断刃３を迎え入れて食品１０を確実に切断することができるように、前記底面受け５１および背面受け５２を含む広い範囲にまたがって深く切り込まれている。図２３などに示すように、食品載置台５には、載置される食品１０の長さ方向両端位置を規制する規制板５６が背面受け５２の両端部に設けられている。一対の規制板５６の間隔は海苔巻き寿司の長さに合致するように調整することができる。 22 and 23, the food mounting table 5 is provided with slits 58 through which the cutting blade 3 can enter at a number and position corresponding to the number of cutting blades 3 and the installation position. Each slit 58 is deeply cut across a wide range including the bottom face receiver 51 and the back face receiver 52 so that the food blade 10 can be reliably cut by receiving the cutting blade 3. As shown in FIG. 23 and the like, the food placing table 5 is provided with restricting plates 56 at both ends of the back support 52 for restricting both end positions in the length direction of the food 10 to be placed. The distance between the pair of regulating plates 56 can be adjusted to match the length of the laver roll sushi.
　次に、図２２ないし図２４に符号６で示す食品載置台の駆動機構について詳細に説明する。食品載置台の駆動機構６を第１の駆動機構とし、後述の受け部材８２の駆動機構を第２の駆動機構として両者を区別する。図２２ないし図２４において、左の側板４の内側面には駆動源としてのモータ６１が固定され、モータ６１の出力軸に固着されたギヤ６２は、軸６４に固着されたギヤ６３と噛み合っている。軸６４は左右の側板４にまたがって回転可能に支持されていて、左右の側板４を貫通した軸６４の両端部にはそれぞれ駆動アーム６５が固着されている。モータ６１の回転駆動力は、ギヤ６２，６３を介して軸６４に伝達され、軸６４と一体の各駆動アーム６５を各側板４の外側面と平行をなす面内において回転駆動するように構成されている。各駆動アーム６５は軸６４の回転中心を通る直線に沿って長孔６６を有している。 Next, the drive mechanism for the food table shown by reference numeral 6 in FIGS. 22 to 24 will be described in detail. The food loading table drive mechanism 6 is used as a first drive mechanism, and a drive mechanism for a receiving member 82 (to be described later) is used as a second drive mechanism. 22 to 24, a motor 61 as a drive source is fixed to the inner side surface of the left side plate 4, and a gear 62 fixed to the output shaft of the motor 61 is engaged with a gear 63 fixed to the shaft 64. Yes. The shaft 64 is rotatably supported across the left and right side plates 4, and drive arms 65 are fixed to both ends of the shaft 64 that penetrates the left and right side plates 4. The rotational driving force of the motor 61 is transmitted to the shaft 64 through the gears 62 and 63, and is configured to rotationally drive each driving arm 65 integral with the shaft 64 in a plane parallel to the outer surface of each side plate 4. Has been. Each drive arm 65 has a long hole 66 along a straight line passing through the rotation center of the shaft 64.
　図２４に示すように、食品載置台５の底部には、この底部を左右方向にかつ水平に貫通して２本の軸５３，５４が取り付けられている。軸５３，５４は互いに平行で、軸５３は食品載置台５の前後方向中央部に、軸５４は食品載置台５の前後方向後部に配置されている。これら２本の軸５３，５４のうち前側の軸５３の両端部はそれぞれ両側の上記駆動アーム６５の長孔６６に嵌っている。したがって、各駆動アーム６５が軸６４とともに軸６４を中心に回転駆動されると、長孔６６の壁面で軸５３が押され、各駆動アーム６５の回転に伴い、後述のカム溝９１に規制されながら、食品載置台５も移動させられるようになっている。ギヤ６３、駆動アーム６５、軸５３を含む機構部分が、食品載置台を駆動する第１の駆動機構６を構成している。 As shown in FIG. 24, two shafts 53 and 54 are attached to the bottom portion of the food mounting table 5 so as to penetrate the bottom portion in the horizontal direction and horizontally. The shafts 53 and 54 are parallel to each other, the shaft 53 is disposed at the center portion in the front-rear direction of the food placing table 5, and the shaft 54 is disposed at the rear portion in the front-rear direction of the food placing table 5. Of these two shafts 53, 54, both end portions of the front shaft 53 are fitted in the long holes 66 of the drive arm 65 on both sides. Therefore, when each drive arm 65 is rotationally driven around the shaft 64 together with the shaft 64, the shaft 53 is pushed by the wall surface of the long hole 66, and is regulated by a cam groove 91 described later with the rotation of each drive arm 65. However, the food mounting table 5 can also be moved. A mechanism portion including the gear 63, the drive arm 65, and the shaft 53 constitutes a first drive mechanism 6 that drives the food placing table.
　左右の各側板４には、側面から見て互いに重なり合うカム溝９１が形成されている。これらのカム溝９１に、食品載置台５に取り付けられている２本の軸５３，５４の両端部が嵌っていて、２本の軸５３，５４は、各カム溝９１の側壁面で支持されるとともに、カム溝９１に対する食品載置台５のカムフォロワとしても機能する。 The left and right side plates 4 are formed with cam grooves 91 that overlap each other when viewed from the side. Both ends of the two shafts 53 and 54 attached to the food placing table 5 are fitted in these cam grooves 91, and the two shafts 53 and 54 are supported by the side wall surfaces of the cam grooves 91. And also functions as a cam follower of the food placing table 5 with respect to the cam groove 91.
　図２２乃至図２４は、一連の食品切断動作開始前の初期位置を示していいて、各駆動アーム６５がほぼ垂直近くまで最大に立ち上がった姿勢になっている。この態様では、図２４に示すように、食品載置台５が最も高い位置になるように、上記２本の軸５３，５４がカム溝９１の上端部に嵌っている。また、図２５乃至図３３に示すように、カム溝９１の上端部は緩やかな円弧部９２となっていて、この円弧部９２は後ろ側が徐々に低くなっている。そして、上記のように食品載置台５が最も高い位置にあるとき、２本の軸５３，５４は上記円弧部９２にあり、よって、食品載置台５は、後方に僅かに反ったような姿勢をとる。 22 to 24 show an initial position before the start of a series of food cutting operations, and each drive arm 65 is in a posture in which the drive arm 65 stands up to a nearly vertical position. In this embodiment, as shown in FIG. 24, the two shafts 53 and 54 are fitted to the upper end portion of the cam groove 91 so that the food placing table 5 is at the highest position. Further, as shown in FIGS. 25 to 33, the upper end portion of the cam groove 91 is a gentle arc portion 92, and the rear side of the arc portion 92 is gradually lowered. Then, when the food placing table 5 is at the highest position as described above, the two shafts 53 and 54 are in the arc portion 92, so that the food placing table 5 is slightly warped backward. Take.
　上記カム溝９１はまた、図２２、図２６乃至図３２などに示すように、上記円弧部９２から斜め下方に向かう円弧部９３に連続しており、円弧部９３はさらに斜め下方に延びた直線部９４に連続している。食品載置台５が上記初期位置から移動を開始し、食品載置台５とともに食品１０が移動して切断刃３に接触し始めると、上記２本の軸５３，５４が円弧部９３に至る。２本の軸５３，５４が円弧部９３を通るとき、食品載置台５は下方に移動しながら姿勢が徐々に下向きになる。すなわち、食品載置台５と食品１０の伏角が徐々に大きくなり、食品１０に対する切断刃３の進入角度が連続的に変化し、食品１０の切断刃３に対する相対速度が早くなるように、カム溝９１の上記円弧部９３の下側の面が凸面になっている。 As shown in FIGS. 22, 26 to 32, etc., the cam groove 91 is continuous with an arc portion 93 that extends obliquely downward from the arc portion 92, and the arc portion 93 is a straight line extending further obliquely downward. It is continuous with the portion 94. When the food placing table 5 starts to move from the initial position and the food 10 moves together with the food placing table 5 and starts to contact the cutting blade 3, the two shafts 53 and 54 reach the arc portion 93. When the two shafts 53 and 54 pass through the arc portion 93, the posture of the food placing table 5 is gradually lowered while moving downward. That is, the cam groove is formed so that the dip angle between the food placing table 5 and the food 10 gradually increases, the approach angle of the cutting blade 3 with respect to the food 10 continuously changes, and the relative speed of the food 10 with respect to the cutting blade 3 increases. The lower surface of the arc portion 93 of 91 is a convex surface.
　軸５３，５４は、上記円弧部９３を通過した後はカム溝９１の直線部９４に導かれ、食品載置台５は上記の前傾姿勢のままで前述のように上から斜め下に向かって直線状に移動し、切断刃３で食品が切断される。切断された食品１０は次に説明する取り出し部材８に移動し、続いて第１の駆動機構６が逆向きに動作して食品載置台５を原位置に復帰させる。 The shafts 53 and 54 are guided to the straight portion 94 of the cam groove 91 after passing through the circular arc portion 93, and the food placing table 5 is inclined from the top to the bottom as described above while maintaining the forward tilt posture. It moves linearly and the food is cut by the cutting blade 3. The cut food 10 moves to a take-out member 8 described below, and then the first drive mechanism 6 operates in the reverse direction to return the food placing table 5 to the original position.
　このような第１の駆動機構６の往復動作は、例えば、スタートボタンを押すだけで行わせることができる。スタートボタンが押されると、前記モータ６１が正転方向に駆動されて駆動アーム６５が図２４において時計方向に回転駆動される。この駆動アーム６５の回転方向は往動方向であり、往動方向の移動限界を検出するまで前記モータ６１が正転方向に駆動される。駆動アーム６５が往動方向の限界位置に達すると、モータの駆動方向が逆転方向に切り換えられ、駆動アーム６５は復動方向に駆動され、復動方向の移動限界を検出するとモータ６１の駆動を停止する。このようにして駆動アーム６５が往復動することにより、食品載置台５が前述のように姿勢を変えながら下降し、食品載置台５で保持していた食品１０が切断刃３で切断された後、食品載置台５のみが原位置に復帰する。 Such reciprocation of the first drive mechanism 6 can be performed, for example, by simply pressing the start button. When the start button is pressed, the motor 61 is driven in the forward direction, and the drive arm 65 is rotated in the clockwise direction in FIG. The rotation direction of the drive arm 65 is the forward movement direction, and the motor 61 is driven in the forward rotation direction until a movement limit in the forward movement direction is detected. When the drive arm 65 reaches the limit position in the forward movement direction, the motor drive direction is switched to the reverse rotation direction, the drive arm 65 is driven in the backward movement direction, and when the movement limit in the backward movement direction is detected, the motor 61 is driven. Stop. As the drive arm 65 reciprocates in this way, the food placing table 5 descends while changing its posture as described above, and the food 10 held on the food placing table 5 is cut by the cutting blade 3. Only the food mounting table 5 returns to the original position.
　次に、前記食品の受け取り部の構成について詳細に説明する。図２１乃至図２４に示すように、装置の前側下部に、切断後の食品１０の受け部材８が設けられている。受け部材８は、下側が装置の前側に突出する向きに傾斜させて固定された傾斜案内面８４に案内されて上下動する受け取り部８２を有してなる。傾斜案内面８４の前面には、切断された食品１０を傾斜案内面８４に沿って円滑に下降させることができるように、複数のリブ８５が縦方向に平行に形成され、食品１０との滑り抵抗を低減している。 Next, the configuration of the food receiving unit will be described in detail. As shown in FIGS. 21 to 24, a receiving member 8 for the food 10 after cutting is provided at the lower front portion of the apparatus. The receiving member 8 includes a receiving portion 82 that moves up and down while being guided by an inclined guide surface 84 that is fixed so that the lower side protrudes toward the front side of the apparatus. A plurality of ribs 85 are formed on the front surface of the inclined guide surface 84 in parallel to the vertical direction so that the cut food product 10 can be smoothly lowered along the inclined guide surface 84. The resistance is reduced.
　受け部材８の受け取り部８２は、傾斜案内面８４に対し直角方向に、したがって斜め前上に向かって突出している。受け部材８は例えば金属板の折り曲げ成形によって製作されていて、その基部は傾斜案内面８４に案内されて斜めに上下動する摺動部８６となっている。この摺動部８６の左右方向両端部には折り曲げ部８８が形成されている。各折り曲げ部８８は、傾斜案内面８４の両端部に上下方向に形成されている案内溝８７を貫いて傾斜案内面８４の背面側に潜り、さらに傾斜案内面８４の両側方に突出し、摺動部材８９の前面にねじ止めされている。各摺動部材８９は直方体状の部材で、横断面がＵ字形の案内レール９０に案内されて摺動するようになっている。案内レール９０は、左右の側板４の外側面に、傾斜案内面８４と平行になるように、かつ、Ｕ字形断面の開放端を側方に向けて固定されている。各案内レール９０には、受け部材８の上記折り曲げ部８８が摺動部材８９とともに摺動するときの障害にならないように、上記折り曲げ部８８に対する逃げ孔９１が形成されている。 The receiving portion 82 of the receiving member 8 protrudes in a direction perpendicular to the inclined guide surface 84, and thus obliquely upward. The receiving member 8 is manufactured, for example, by bending a metal plate, and a base portion thereof is a sliding portion 86 that is guided by the inclined guide surface 84 and moves up and down obliquely. Bending portions 88 are formed at both left and right end portions of the sliding portion 86. Each bent portion 88 passes through a guide groove 87 formed in the vertical direction at both ends of the inclined guide surface 84, lies on the back side of the inclined guide surface 84, protrudes on both sides of the inclined guide surface 84, and slides. Screwed to the front surface of the member 89. Each sliding member 89 is a rectangular parallelepiped member, and is slid by being guided by a guide rail 90 having a U-shaped cross section. The guide rail 90 is fixed to the outer side surfaces of the left and right side plates 4 so as to be parallel to the inclined guide surface 84 and with the open end of the U-shaped cross section facing sideways. Each guide rail 90 is formed with a relief hole 91 for the bent portion 88 so as not to be an obstacle when the bent portion 88 of the receiving member 8 slides together with the sliding member 89.
　受け部材８は、左右一対のリンクアーム３０が回転することによって駆動されるようになっている。各リンクアーム３０は、左右の側板４の外側面下方寄りの位置に、共通の軸３１を中心にして側板４と平行をなす垂直面内で回転可能に取り付けられている。本実施例に係る食品切断装置を正面から見て左側の側板４に取り付けられているリンクアーム３０の基端部には、軸３１と同心円をなす小ギヤ３２が固着されている。各リンクアーム３０の先端部には軸３１の中心を通る線に沿った長孔３３が形成され、各長孔３３には、各摺動部材８９の側面に植えられているピン３４が嵌っている。したがって、リンクアーム３０が回転駆動されると、その長孔３３の側壁によってピン３４が押され、ピン３４とともに受け部材８２が案内レール９０に案内されながら斜め上下方向に上昇し下降するように構成されている。 The receiving member 8 is driven by the rotation of the pair of left and right link arms 30. Each link arm 30 is attached to a position closer to the lower side of the outer surface of the left and right side plates 4 so as to be rotatable within a vertical plane that is parallel to the side plates 4 with a common axis 31 as the center. A small gear 32 concentric with the shaft 31 is fixed to the base end portion of the link arm 30 attached to the left side plate 4 when the food cutting apparatus according to the present embodiment is viewed from the front. A long hole 33 along a line passing through the center of the shaft 31 is formed at the tip of each link arm 30, and a pin 34 planted on the side surface of each sliding member 89 is fitted in each long hole 33. Yes. Therefore, when the link arm 30 is rotationally driven, the pin 34 is pushed by the side wall of the elongated hole 33, and the receiving member 82 is guided to the guide rail 90 together with the pin 34 so as to rise and fall obliquely in the vertical direction. Has been.
　この実施例では、リンクアーム３０の駆動源はモータ６１で、以下のような連携機構および第２の駆動機構を介してモータ６１の駆動力がリンクアーム３０に伝達されるようになっている。前記各駆動アーム６５の長さ方向中央付近の外側面にはピン６８が植えられている。駆動アーム６５の回転中心である前記軸６４によって扇形の大ギヤ２０が保持されている。大ギヤ２０は、扇の中心に相当する位置に軸６４があり、軸６４を中心とした円弧に沿ってギヤが形成されている。大ギヤ２０は、軸６４に対しては相対回転自在となっており、ギヤ形成部分は上記小ギヤ３２と噛み合っている。 In this embodiment, the drive source of the link arm 30 is the motor 61, and the driving force of the motor 61 is transmitted to the link arm 30 through the following linkage mechanism and the second drive mechanism. A pin 68 is planted on the outer surface near the center in the length direction of each drive arm 65. The fan-shaped large gear 20 is held by the shaft 64 which is the rotation center of the drive arm 65. The large gear 20 has a shaft 64 at a position corresponding to the center of the fan, and a gear is formed along an arc centered on the shaft 64. The large gear 20 is rotatable relative to the shaft 64, and the gear forming portion meshes with the small gear 32.
　扇形の大ギヤ２０には、図２４において上側の側面に、三角形状の連携板４０が固着されている。連携板４０は、駆動アーム６５の長さ方向に対し略直交する方向に長孔４１を有している。この長孔４１には駆動アーム６５のピン６８が嵌っている。ただし、ピン６８の外径に対して長孔４１の幅は十分に大きく、ピン６８が長孔４１の長さ方向の範囲内で移動するときは長孔４１を画する壁面に接することはなく、ピン６８が長孔４１の長さ方向両端に至ったとき、大ギヤ２０を駆動するようになっている。 24. A triangular linkage plate 40 is fixed to the fan-shaped large gear 20 on the upper side surface in FIG. The link plate 40 has a long hole 41 in a direction substantially orthogonal to the length direction of the drive arm 65. A pin 68 of the drive arm 65 is fitted in the long hole 41. However, the width of the long hole 41 is sufficiently large with respect to the outer diameter of the pin 68, and when the pin 68 moves within the range of the length direction of the long hole 41, it does not contact the wall surface that defines the long hole 41. When the pin 68 reaches both ends of the long hole 41 in the length direction, the large gear 20 is driven.
　図２４に示す態様では、駆動アーム６５が反時計方向に最大限回転し、前述のように食品載置台５が最上位まで移動して食品１０を受け入れる姿勢をとっている。この態様では、上記ピン６８が連携板４０の長孔４１の一端にあって連携板４０を引き上げ、連携板４０と一体の大ギヤ２０を、軸６４を中心に反時計方向に回転させている。大ギヤ２０の回転力は小ギヤ３２に伝達され、小ギヤ３２を回転させる。図２４に示す態様では、小ギヤ３２が時計方向に最大限回転させられ、小ギヤ３２と一体的に時計方向に回転したリンクアーム３０によって摺動部材８９が限界位置まで下降している。摺動部材８９は下降限界位置で下部のストッパ３５に当たって移動が制限され、摺動部材８９と一体の受け部材８２とともに下降位置が安定に保持されるようになっている。 24, the drive arm 65 is rotated to the maximum in the counterclockwise direction, and the food placing table 5 is moved to the uppermost position to receive the food 10 as described above. In this embodiment, the pin 68 is located at one end of the long hole 41 of the linkage plate 40, pulling up the linkage plate 40, and rotating the large gear 20 integrated with the linkage plate 40 counterclockwise about the shaft 64. . The rotational force of the large gear 20 is transmitted to the small gear 32 to rotate the small gear 32. In the mode shown in FIG. 24, the small gear 32 is rotated to the maximum in the clockwise direction, and the sliding member 89 is lowered to the limit position by the link arm 30 that rotates integrally with the small gear 32 in the clockwise direction. The movement of the sliding member 89 is restricted by hitting the lower stopper 35 at the lower limit position, and the lowering position is stably held together with the receiving member 82 integrated with the sliding member 89.
　駆動アーム６５が、図２４に示す位置から時計方向に回転駆動され、図２６に示すようにピン６８が大ギヤ２０の上縁に当たるまでは、ピン６８は連携板４０の長孔４１内を、円弧を描きながら移動するだけで、ピン６８に連動する部材はない。図２６に示す動作態様は食品１０が切断刃３で約半分切断された態様にある。図２６に示す動作態様からさらに駆動アーム６５が時計方向に回転するにしたがい、ピン６８が大ギヤ２０の上縁を押し、大ギヤ２０を時計方向に回転させる。この大ギヤ２０の回転力は小ギヤ３２に伝達され、小ギヤ３２は反時計方向に回転駆動され、この回転力がリンクアーム３０に伝達されてリンクアーム３０が軸３１を中心に反時計方向に回転駆動される。図２７乃至図２９は大ギヤ２０の時計方向回転による小ギヤ３２およびリンクアーム３０の反時計方向回転を示している。このリンクアーム３０の反時計方向への回転により長孔３３とピン３４を介して摺動部材８９およびこれと実質一体の受け部材８が、傾斜案内面８４に案内されて斜め上方に押し上げられるようになっている。駆動アーム６５のピン６８、連携板４０、ギヤ列２０，３２を含む構成部分は、第１の駆動機構６から、受け部材８を駆動する第２の駆動機構に駆動力を伝達する連携機構を構成している。 The drive arm 65 is driven to rotate clockwise from the position shown in FIG. 24, and until the pin 68 hits the upper edge of the large gear 20 as shown in FIG. There is no member linked to the pin 68 just by moving while drawing an arc. The operation mode shown in FIG. 26 is a mode in which the food 10 is cut about half by the cutting blade 3. As the driving arm 65 further rotates clockwise from the operation mode shown in FIG. 26, the pin 68 pushes the upper edge of the large gear 20 and rotates the large gear 20 clockwise. The rotational force of the large gear 20 is transmitted to the small gear 32, and the small gear 32 is rotationally driven in the counterclockwise direction. This rotational force is transmitted to the link arm 30, and the link arm 30 is counterclockwise about the shaft 31. Is driven to rotate. 27 to 29 show the counterclockwise rotation of the small gear 32 and the link arm 30 caused by the clockwise rotation of the large gear 20. By the rotation of the link arm 30 in the counterclockwise direction, the sliding member 89 and the receiving member 8 substantially integrated therewith are guided through the inclined guide surface 84 via the elongated hole 33 and the pin 34 so as to be pushed upward obliquely. It has become. The components including the pin 68 of the drive arm 65, the linkage plate 40, and the gear trains 20 and 32 include a linkage mechanism that transmits a driving force from the first drive mechanism 6 to the second drive mechanism that drives the receiving member 8. It is composed.
　リンクアーム３０の長さと食品載置台５の上下方向の移動距離との比に対して、大ギヤ２０と小ギヤ３２のギヤ比を大きくし、大ギヤ２０の回転角度の割には小ギヤ３２の回転角度が十分に大きくなるように設計されている。しかし、摺動部材８９および食品載置台５が実際に移動することができるストロークは限られているので、小ギヤ３２が食品載置台５の必要なストローク分を越えて回転駆動されるときは、小ギヤ３２とリンクアーム３０との間で滑りが生じるように、滑り機構が設けられている。滑り機構はトルクリミッタともいわれている。滑り機構の具体的な構成は図示していないが、周知の構成を適宜選択して採用すればよい。例えば、小ギヤ３２とリンクアーム３０との間に反発コイルばねを介在させることにより滑り機構を構成してもよい。 The gear ratio of the large gear 20 and the small gear 32 is increased with respect to the ratio of the length of the link arm 30 and the vertical movement distance of the food placing table 5, and the small gear 32 for the rotation angle of the large gear 20. The rotation angle is designed to be sufficiently large. However, since the stroke that the sliding member 89 and the food placing table 5 can actually move is limited, when the small gear 32 is rotationally driven beyond the necessary stroke of the food placing table 5, A slip mechanism is provided so that slip occurs between the small gear 32 and the link arm 30. The sliding mechanism is also called a torque limiter. Although a specific configuration of the sliding mechanism is not illustrated, a known configuration may be appropriately selected and adopted. For example, the sliding mechanism may be configured by interposing a repulsive coil spring between the small gear 32 and the link arm 30.
　図２８に示す態様では、摺動部材８９が上部のストッパ３６に当たり、摺動部材８９および食品受け台５が上昇限界位置にある。摺動部材８９がストッパ３６に当たってもなお図２９、図３０に示すように大ギヤ２０が時計方向に回転し、小ギヤ３２が反時計方向に回転駆動される。しかし、摺動部材８９が移動限界に達しているので、リンクアーム３０は回転することができず、上記滑り機構で駆動部材８９の余分な移動ストロークを吸収するようになっている。 28, the sliding member 89 hits the upper stopper 36, and the sliding member 89 and the food cradle 5 are at the ascent limit position. Even when the sliding member 89 hits the stopper 36, the large gear 20 rotates clockwise as shown in FIGS. 29 and 30, and the small gear 32 is driven to rotate counterclockwise. However, since the sliding member 89 has reached the movement limit, the link arm 30 cannot rotate, and the sliding mechanism absorbs an extra movement stroke of the driving member 89.
　リンクアーム３０は、本実施例に係る食品切断装置を正面から見て左右両側に設けられて食品載置台５を左右両側から駆動するようになっている。これに対して、一対のリンクアーム３０に駆動力を伝達する連携板４０、大ギヤ２０、小ギヤ３２および前記滑り機構は、本装置の左側にのみ設けられている。一対のリンクアーム３０は共通の軸３１で一体に結合されて一対のリンクアーム３０が一体として駆動されるようになっている。上記ピン６８から、連携板４０、ギヤ列２０、３２を含む構成部分が前述のように連携機構を構成しており、小ギヤ３２、リンクアーム３０、摺動部材８９の軸３４に至る機構は、受け部材８を上下方向に駆動するための第２の機構を構成している。この第２の駆動機構内に上記滑り機構が組み込まれている。 The link arm 30 is provided on both the left and right sides of the food cutting device according to the present embodiment when viewed from the front, and drives the food placing table 5 from the left and right sides. In contrast, the linkage plate 40, the large gear 20, the small gear 32, and the sliding mechanism that transmit the driving force to the pair of link arms 30 are provided only on the left side of the apparatus. The pair of link arms 30 are integrally coupled by a common shaft 31 so that the pair of link arms 30 are driven integrally. The components including the linkage plate 40 and the gear trains 20 and 32 from the pin 68 constitute a linkage mechanism as described above, and the mechanism from the small gear 32, the link arm 30 and the shaft 34 of the sliding member 89 is as follows. A second mechanism for driving the receiving member 8 in the vertical direction is configured. The sliding mechanism is incorporated in the second drive mechanism.
　次に、以上のように構成されている実施例の一連の動作を説明する。図２２乃至図２４は動作開始前の初期状態を示している。駆動アーム６５は図２４において反時計方向への回転限界位置にあって、最も立ち上がった姿勢になっている。食品載置台５は２本の軸５３，５４がカム溝９１の上側終端部の円弧部９２にあって切断前の食品１０の載置姿勢をとっている。駆動アーム６５のピン６８が連携板４０長孔４１の一端に当たり、連携板４０とともに大ギヤ２０を図２４において反時計方向に回転させている。この大ギヤ２０の回転により小ギヤ３０は図２４において時計方向に回転し、摺動部材８９、受け部材８２が下方への移動限界位置にある。 Next, a series of operations of the embodiment configured as described above will be described. 22 to 24 show an initial state before the operation is started. The drive arm 65 is in the counterclockwise rotation limit position in FIG. 24 and is in the most upright posture. The food placing table 5 has two shafts 53 and 54 in the arc portion 92 at the upper end of the cam groove 91 to take the placing posture of the food 10 before cutting. The pin 68 of the drive arm 65 hits one end of the long hole 41 of the cooperation plate 40, and the large gear 20 is rotated counterclockwise in FIG. Due to the rotation of the large gear 20, the small gear 30 rotates in the clockwise direction in FIG. 24, and the sliding member 89 and the receiving member 82 are at the downward movement limit position.
　上記初期状態において、食品載置台５に食品１０を載置し、スタートボタンを操作すると、モータ６１が起動され、第１の駆動機構６が作動を開始する。ギヤ列６２，６３、軸６４を経て第１の駆動機構６の駆動アーム６５が図２５に示すように時計方向に回転駆動され、その長孔６６に嵌っている食品載置台５の軸５３がカム溝９１に沿って移動させられる。軸５３とともに軸５４もカム溝９１に沿って移動する。軸５３、５４がカム溝９１の円弧部９３の位置にさしかかると、軸５３の高さ位置が軸５４の高さ位置に対して連続的に低くなり、もって、食品載置台５が前傾姿勢をとるとともに前傾姿勢が徐々に深くなる。 In the initial state, when the food 10 is placed on the food placing table 5 and the start button is operated, the motor 61 is activated and the first drive mechanism 6 starts operating. The drive arm 65 of the first drive mechanism 6 is driven to rotate clockwise as shown in FIG. 25 through the gear trains 62 and 63 and the shaft 64, and the shaft 53 of the food mounting table 5 fitted in the long hole 66 is moved. It is moved along the cam groove 91. The shaft 54 moves along the cam groove 91 together with the shaft 53. When the shafts 53, 54 reach the position of the arc portion 93 of the cam groove 91, the height position of the shaft 53 is continuously lowered with respect to the height position of the shaft 54, so that the food placing table 5 is tilted forward. The forward leaning posture gradually deepens.
　上記のように、食品載置台５が前傾姿勢をとり始める位置は、食品１０が切断刃３に接触し始めるときである。食品１０と切断刃３の接触開始当初は、食品１０に対する切断刃３の進入角度を連続的に変化させて切断刃３と食品１０の相対速度を速めるようになっている。図２５はこのときの動作態様示している。こうして切断開始当初の食品１０への切断刃３の進入を容易にし、食品１０の切断が円滑に行われるように工夫されている。 As described above, the position where the food placing table 5 starts to take the forward tilting posture is when the food 10 starts to contact the cutting blade 3. At the beginning of contact between the food 10 and the cutting blade 3, the relative angle between the cutting blade 3 and the food 10 is increased by continuously changing the approach angle of the cutting blade 3 with respect to the food 10. FIG. 25 shows an operation mode at this time. Thus, the cutting blade 3 is made easy to enter the food 10 at the beginning of cutting, and the food 10 is cut smoothly.
　食品載置台５の軸５３、５４がカム溝９１の直線部９４に至ると、食品載置台５は最大の傾斜角度を保ったまま上記直線部９４に沿って斜め下方に移動する。この間、垂直方向に両持ち状に固定された切断刃３と交差しながら、食品載置台５とともに食品１０が斜め下方に一定の相対速度で移動し、食品１０が輪切り状に切断される。図２６乃至図３０はこの作動態様を示しており、図３０は切断完了直後の状態を示している。食品載置台５には、前述の通り、切断歯３に対する逃げ溝が形成されている。 When the shafts 53 and 54 of the food placing table 5 reach the straight portion 94 of the cam groove 91, the food placing table 5 moves obliquely downward along the straight portion 94 while maintaining the maximum inclination angle. During this time, while crossing the cutting blade 3 that is fixed in a doubly supported manner in the vertical direction, the food 10 moves obliquely downward with a constant relative speed together with the food mounting table 5, and the food 10 is cut into a circular shape. 26 to 30 show this operation mode, and FIG. 30 shows a state immediately after the completion of cutting. As described above, the food placing table 5 is provided with a relief groove for the cutting teeth 3.
　図２６は、食品１０の切断工程の途中であって食品１０が約半分切断され、駆動アーム６５のピン６８が大ギヤ２０に当たり始めた動作態様を示している。駆動アーム６５がさらに回転することにより、前記連携機構が機能し始め、前記第２の駆動機構に駆動力を伝達する。すなわち、ピン６８が大ギヤ２０を下に向かって押し、大ギヤ２０を、図２７、図２８、図２９に示すように時計方向に回転させる。大ギヤ２０の回転力は第２の駆動機構の一部を構成している小ギヤ３２に伝達され、小ギヤ３２を反時計方向に回転させる。小ギヤ３２の回転力は、前記滑り機構を介してリンクアーム３０に伝達され、リンクアーム３０は反時計方向に回転駆動される。このリンクアーム３０の回転により摺動部材８９および受け部材８が、傾斜案内面８４および案内レール９０に案内されて斜め上方に押し上げられる。図２７は受け部材８が斜め上方に上昇している途中の態様を、図２８は受け部材８が上側のストッパ３６に当たる限界位置まで上昇した態様を示している。 FIG. 26 shows an operation mode in which the food 10 is cut about half during the cutting process of the food 10 and the pin 68 of the drive arm 65 starts to hit the large gear 20. When the driving arm 65 further rotates, the cooperation mechanism starts to function, and the driving force is transmitted to the second driving mechanism. That is, the pin 68 pushes the large gear 20 downward, causing the large gear 20 to rotate clockwise as shown in FIGS. The rotational force of the large gear 20 is transmitted to the small gear 32 that constitutes a part of the second drive mechanism, causing the small gear 32 to rotate counterclockwise. The rotational force of the small gear 32 is transmitted to the link arm 30 via the sliding mechanism, and the link arm 30 is driven to rotate counterclockwise. By the rotation of the link arm 30, the sliding member 89 and the receiving member 8 are guided by the inclined guide surface 84 and the guide rail 90 and pushed upward obliquely. 27 shows a state in which the receiving member 8 is rising obliquely upward, and FIG. 28 shows a state in which the receiving member 8 is raised to a limit position where it hits the upper stopper 36.
　前記カム溝９１の直線部９４の傾斜角度と案内レール９０の傾斜角度は同じ角度になっていて、上記直線部９４に沿った食品載置台５の上下移動方向と案内レール９０に沿った受け部材８の上下移動方向は平行になっている。そして、図２８に示すように、受け部材８が上側の限界位置まで上昇すると、食品載置台５に載置されて食品載置台５とともに斜めに下降してくる食品１０の移動方向前方に受け取り部８２が位置して、食品１０を受け取る態勢をとっている。 The inclination angle of the linear portion 94 of the cam groove 91 and the inclination angle of the guide rail 90 are the same, and the vertical movement direction of the food placing table 5 along the linear portion 94 and the receiving member along the guide rail 90 The vertical movement direction of 8 is parallel. Then, as shown in FIG. 28, when the receiving member 8 is raised to the upper limit position, the receiving portion is placed on the front side of the moving direction of the food 10 that is placed on the food placing table 5 and descends obliquely together with the food placing table 5. 82 is located and is ready to receive food 10.
　受け部材８が上側の限界位置まで上昇したのちもなお駆動アーム６５が図２９に示すように時計方向に回転駆動され、駆動アーム６５は軸５３を下降させる。軸５３は軸５４とともにカム溝９１の直線部９４に沿って下降し、食品載置台５は食品１０を保持しかつ前傾姿勢を保ったまま斜め下方に向かって移動する。図２９は、食品載置台５で保持されている食品１０の切断完了直前の動作態様を示している。この動作態様では、食品載置台５が上記のように移動し、食品載置台５に保持されている食品１０が受け部材８の受け取り部８２に接している。 After the receiving member 8 is raised to the upper limit position, the drive arm 65 is still driven to rotate clockwise as shown in FIG. 29, and the drive arm 65 lowers the shaft 53. The shaft 53 moves down along the straight portion 94 of the cam groove 91 together with the shaft 54, and the food placing table 5 moves obliquely downward while holding the food 10 and maintaining the forward tilting posture. FIG. 29 shows an operation mode immediately before the cutting of the food 10 held on the food placing table 5 is completed. In this operation mode, the food placing table 5 moves as described above, and the food 10 held on the food placing table 5 is in contact with the receiving portion 82 of the receiving member 8.
　食品１０の太さが図示のものより大きい場合は、受け部材８が上昇限界に達する前に受け部材８の受け取り部８２に食品１０が接触し、受け部材８は下降してくる食品１０で押し下げられる。この押し下げ力で摺動部材６５と受け部材８が下方に押し下げられ、リンクアーム３０が図２９において時計方向に強制的に押し戻される。このリンクアーム３０の強制的な時計方向への回転は、リンクアーム３０と小ギヤ３２との間の前記滑り機構が滑ることによって許容される。 When the thickness of the food 10 is larger than that shown in the drawing, the food 10 comes into contact with the receiving portion 82 of the receiving member 8 before the receiving member 8 reaches the rising limit, and the receiving member 8 is pushed down by the lowering food 10. It is done. With this pressing force, the sliding member 65 and the receiving member 8 are pressed downward, and the link arm 30 is forcibly pushed back clockwise in FIG. The forced clockwise rotation of the link arm 30 is allowed by the sliding mechanism between the link arm 30 and the small gear 32 sliding.
　切断歯３による食品１０の切断が完了したのちも駆動アーム６５は時計方向に回転駆動され、図３０に示す時計方向への回転限界に至る。図２９に示す動作態様から図３０に示す動作態様に至る間、駆動アーム６５の長孔６６と軸５３の嵌り合いによって食品載置台５はなおも斜め下方に下降する。食品載置台５とともに食品１０も下降するため、食品１０の切断が完了するとともに、受け部材８も食品１０に押されて下降する。上記駆動アーム６５が時計方向に回転すると、ピン６８によって大ギヤ２０が時計方向に回転させられ、小ギヤ３２が反時計方向に回転させられる。しかし、小ギヤ３２とリンクアーム３０との間に上記滑り機構が介在しているため、小ギヤ３２の回転力はリンクアーム３０に伝達されず、上記強制的な受け部材８の下降によるリンクアーム３０の時計方向への回転が許容される。 After the cutting of the food 10 by the cutting teeth 3 is completed, the driving arm 65 is driven to rotate in the clockwise direction, reaching the clockwise limit shown in FIG. During the operation mode shown in FIG. 29 to the operation mode shown in FIG. 30, the food placing table 5 still moves downward obliquely due to the fitting of the long hole 66 of the drive arm 65 and the shaft 53. Since the food 10 is lowered together with the food placing table 5, the cutting of the food 10 is completed, and the receiving member 8 is pushed by the food 10 and lowered. When the drive arm 65 rotates in the clockwise direction, the large gear 20 is rotated in the clockwise direction by the pin 68, and the small gear 32 is rotated in the counterclockwise direction. However, since the sliding mechanism is interposed between the small gear 32 and the link arm 30, the rotational force of the small gear 32 is not transmitted to the link arm 30, and the link arm is caused by the forced lowering of the receiving member 8. Thirty clockwise rotations are allowed.
　このようにして食品１０の切断が完了し、食品１０の受け部材８への受け渡しが完了した動作態様に至ると、前記モータ６１の回転方向が逆向きに切り換えられる。図３１は、モータ６１が逆転し始め、駆動アーム６５が反時計方向に回転して初期位置の方に向かい戻っている途中の状態を示している。駆動アーム６５の戻し動作に伴い、食品載置台６５の軸５３と駆動アーム６５の長孔６６の嵌り合いにより食品載置台６５がカム溝９１に沿って上昇する。駆動アーム６５の戻り動作の途中までは、駆動アーム６５が有するピン６８は連携板４０の長孔４１の幅と長さの範囲内で円弧を描いて移動するだけで、連携板４０には作用しない。よって、大ギヤ２０は回転せず、リンクアーム３０、受け部材８も動かない。 In this way, when the cutting of the food 10 is completed and the operation mode in which the delivery of the food 10 to the receiving member 8 is completed, the rotation direction of the motor 61 is switched to the opposite direction. FIG. 31 shows a state in which the motor 61 starts to reversely rotate and the drive arm 65 is rotating counterclockwise and returning toward the initial position. As the driving arm 65 returns, the food mounting table 65 rises along the cam groove 91 due to the fitting of the shaft 53 of the food mounting table 65 and the long hole 66 of the driving arm 65. Until the return operation of the drive arm 65, the pin 68 of the drive arm 65 simply moves in a circular arc within the range of the width and length of the long hole 41 of the linkage plate 40, and acts on the linkage plate 40. do not do. Therefore, the large gear 20 does not rotate, and the link arm 30 and the receiving member 8 do not move.
　駆動アーム６５が反時計方向に回転し、食品載置台５が初期位置に戻る途中で、駆動アーム６５のピン６８が連携板４０の長孔４１の一端に至ると、前記第２の駆動機構が逆向きに動作する。すなわち、図３３に示すようにピン６８と連携板４０を介して大ギヤ２０が反時計方向に回転駆動される。この大ギヤ２０の回転により小ギヤ３２が時計方向に回転駆動され、前記滑り機構を介して駆動力がリンクアーム３０に伝達され、リンクアーム３０が時計方向に回転駆動される。このリンクアーム３０の回転により摺動部材８９とともに受け部材８が斜め下方に下降し、摺動部材８９がストッパ３５に当たり、摺動部材８９および受け部材８の下降限界位置に至る。この受け部材８の下降限界位置において、受け部材８の受け取り部８２で支持されている切断済みの食品１０が取り出し部にあり、食品１０を取り出すことができる。 When the drive arm 65 rotates counterclockwise and the food placing table 5 returns to the initial position, when the pin 68 of the drive arm 65 reaches one end of the long hole 41 of the linkage plate 40, the second drive mechanism is Operate in the opposite direction. That is, as shown in FIG. 33, the large gear 20 is driven to rotate counterclockwise via the pin 68 and the linkage plate 40. Due to the rotation of the large gear 20, the small gear 32 is rotationally driven in the clockwise direction, the driving force is transmitted to the link arm 30 through the sliding mechanism, and the link arm 30 is rotationally driven in the clockwise direction. The rotation of the link arm 30 causes the receiving member 8 together with the sliding member 89 to descend obliquely downward, the sliding member 89 hits the stopper 35, and reaches the lower limit position of the sliding member 89 and the receiving member 8. At the lower limit position of the receiving member 8, the cut food 10 supported by the receiving portion 82 of the receiving member 8 is in the take-out portion, and the food 10 can be taken out.
　受け部材８が下降限界位置に至った後も、駆動アーム６５は図３３において反時計方向に駆動され、食品載置台５が図４４に示す初期位置に戻ることによりモータ６１の駆動が停止して一連の動作が停止する。図３３に示す復帰動作の途中から図３４に示す初期位置への復帰までの間、ピン６８によって大ギヤ２０が反時計方向に、小ギヤ３２が時計方向に回転駆動されリンクアーム３０に時計方向の回転トルクがかかる。しかし、リンクアーム３０はストッパ３５によって回転が制限され、前記滑り機構によって小ギヤ３２とリンクアーム３２が滑り、受け部材８は取り出し部に位置したままである。 Even after the receiving member 8 reaches the lower limit position, the drive arm 65 is driven in the counterclockwise direction in FIG. 33, and the drive of the motor 61 is stopped when the food placing table 5 returns to the initial position shown in FIG. A series of operations stops. 33, until the return to the initial position shown in FIG. 34, the large gear 20 is rotated counterclockwise by the pin 68 and the small gear 32 is rotated clockwise by the pin 68 to the link arm 30 in the clockwise direction. The rotational torque is applied. However, the rotation of the link arm 30 is limited by the stopper 35, and the small gear 32 and the link arm 32 are slid by the sliding mechanism, and the receiving member 8 remains in the take-out portion.
　取り出し部にある受け部材８から切断済みの食品１０を取り出し、装置の上部の食品供給部に移動している食品載置台５に食品１０を載せ、再びスタートスイッチを押すと、上に述べた一連の動作を経て食品１０が切断され、切断された食品１０は取り出し部８に至る。 When the cut food 10 is taken out from the receiving member 8 in the take-out section, placed on the food placing table 5 moving to the food supply section in the upper part of the apparatus, and the start switch is pushed again, the above-described series The food 10 is cut through the operations described above, and the cut food 10 reaches the take-out unit 8.
　以上説明した実施例に係る食品切断装置は、切断後の食品１０をその重力で落下させるのではなく、受け部材８で受け取りに行き、食品１０を受け取った受け部材８を取り出し部まで下降させるように構成されている。したがって、切断後の食品１０は所定の姿勢を保ったまま取り出し部に至るため、切断後の食品取り出しの作業性をより一層向上させることができる。また、取り出し部に至った食品１０の姿勢がそろっているため、見た目もきれいである。 The food cutting device according to the embodiment described above does not drop the food 10 after being cut by its gravity, but instead receives it by the receiving member 8 and lowers the receiving member 8 that has received the food 10 to the take-out portion. It is configured. Therefore, since the food 10 after cutting reaches the take-out portion while maintaining a predetermined posture, the workability of taking out the food after cutting can be further improved. Moreover, since the attitude | position of the foodstuff 10 which reached the taking-out part has gathered, the appearance is also beautiful.
　上記実施例によれば、切断後の食品１０の受け部材８は、第２の駆動機構を構成するリンクアーム３０の回転によって駆動されるようになっており、リンクアーム３０とこれに駆動力を伝達する小ギヤ３２との間には滑り機構が介在している。そして、小ギヤ３２はリンクアーム３０を十分大きな回転角度で回転駆動することができるようにし、リンクアーム３０の余分な回転角度は、滑り機構を滑らせることによって吸収するように構成されている。したがって、受け部材８の移動ストロークを長くし、小さいサイズの食品を受けることができるようにしておけば、食品サイズの大小に対応することができる。また、大きいサイズの食品を受ける場合のように、受け部材８の移動ストロークが短くて済む場合は、上記滑り機構を滑らせながら大きいサイズの食品で受け部材８を押し戻すため、大きいサイズの切断後の食品を、食品載置台１０と受け部材８との間で押し潰すことなく、形が整ったまま取り出すことができる。また、受け部材８の移動ストロークは機械的なストッパで規制すればよく、電気的なセンサの類および複雑な電気的制御回路は不要であるから、操作性の良い食品切断装置を低コストで提供することができる。 According to the above embodiment, the receiving member 8 of the food 10 after being cut is driven by the rotation of the link arm 30 constituting the second drive mechanism, and the link arm 30 and the driving force are applied to this. A sliding mechanism is interposed between the small gear 32 for transmission. The small gear 32 is configured so that the link arm 30 can be driven to rotate at a sufficiently large rotation angle, and the extra rotation angle of the link arm 30 is absorbed by sliding the sliding mechanism. Therefore, if the moving stroke of the receiving member 8 is lengthened so that small size food can be received, the size of the food can be accommodated. Further, when the movement stroke of the receiving member 8 is short as in the case of receiving a large size food, the receiving member 8 is pushed back with the large size food while sliding the sliding mechanism. The food product can be taken out with its shape in place without being crushed between the food placing table 10 and the receiving member 8. In addition, the movement stroke of the receiving member 8 may be regulated by a mechanical stopper, and no electric sensor or complicated electric control circuit is required. Therefore, a food cutting device with good operability is provided at low cost. can do.
　食品載置台５の駆動源と切断後の食品１０を受け取る受け部材８の駆動源は共通のモータ６１でありコストの低減を図っている。そして、駆動減の共通化を図るために、食品載置台５の駆動機構６と受け部材８を駆動する第２の駆動機構とを、連携機構を介して連携させ、食品載置台５の駆動による食品切断行程の途中から、受け部材８を食品受け取り位置まで上昇させるように構成されている。さらに、第１の駆動機構６と受け部材８を駆動する第２の駆動機構との移動ストロークの差を吸収するために、第２の駆動機構内に滑り機構を設けている。このような食品受け取り機構を設けることにより、前述のように、切断後の食品取り出しの作業性をより一層向上させることができる。 The drive source of the food placing table 5 and the drive source of the receiving member 8 that receives the cut food 10 are a common motor 61 to reduce the cost. Then, in order to make the drive reduction common, the driving mechanism 6 of the food placing table 5 and the second driving mechanism that drives the receiving member 8 are linked through the linkage mechanism, and the food placing table 5 is driven. It is comprised so that the receiving member 8 may be raised to a food receiving position from the middle of a food cutting process. Furthermore, a slip mechanism is provided in the second drive mechanism in order to absorb the difference in movement stroke between the first drive mechanism 6 and the second drive mechanism that drives the receiving member 8. By providing such a food receiving mechanism, it is possible to further improve the workability of food removal after cutting as described above.
　図３５は、本発明に係る食品切断装置の第３の実施例を示す。この実施例は、食品載置台５の駆動機構すなわち第１の駆動機構６と、切断後の食品１０の受け部材８の駆動機構すなわち第２の駆動機構とを連携する連携機構がなく、上記第１の駆動機構と第２の駆動機構が個別に駆動源を備えていることが前記第２の実施例と異なっている。なお、図３５において、前記第１の実施例の構成部分と同じ構成部分には同じ符号を付し、同じ構成部分の説明は簡略化する。 FIG. 35 shows a third embodiment of the food cutting device according to the present invention. In this embodiment, there is no linkage mechanism that links the drive mechanism of the food placing table 5, that is, the first drive mechanism 6, and the drive mechanism of the receiving member 8 of the food 10 after cutting, that is, the second drive mechanism. The difference between the first embodiment and the second embodiment is that the first drive mechanism and the second drive mechanism each have a drive source. In FIG. 35, the same components as those of the first embodiment are denoted by the same reference numerals, and the description of the same components will be simplified.
　図３５において、食品載置台５の駆動機構６、すなわち第１の駆動機構は、前記実施例と同様に、駆動源としてのモータ６１、ギヤ６２，６３、駆動アーム６５、食品載置台５を貫く２本の軸５３，５４、側板４に形成されているカム溝９１を有している。駆動アーム６５の回転による食品載置台５の動作および切断刃３による食品１０の切断動作は、第１の実施例と同じである。 In FIG. 35, the driving mechanism 6 of the food placing table 5, that is, the first driving mechanism penetrates the motor 61, the gears 62 and 63, the driving arm 65, and the food placing table 5 as the driving source, as in the above embodiment. Two shafts 53 and 54 and a cam groove 91 formed in the side plate 4 are provided. The operation of the food placing table 5 by the rotation of the drive arm 65 and the cutting operation of the food 10 by the cutting blade 3 are the same as in the first embodiment.
　切断後の食品１０の受け部材８を駆動する第２の駆動機構の駆動源として、上記モータ６１とは別のモータ１０１を備えている。モータ１０１の出力軸にはギヤ１０２が固着されていて、ギヤ１０２はギヤ３２と噛み合っている。ギヤ３２は前記実施例と同様に軸３１を回転中心としており、軸３１にはまた、この軸３１を回転中心とするリンクアーム３０が嵌められている。リンクアーム３０とギヤ３２との間には、前記実施例と同様に滑り機構が設けられている。リンクアーム３０は、前記実施例と同様に摺動部材８９と、長孔とピンによって連携され、摺動部材８９は受け部材８と実質一体に結合されている。モータ１０１からリンクアーム３０に至る駆動機構が第２の駆動機構を構成している。 A motor 101 different from the motor 61 is provided as a drive source of the second drive mechanism that drives the receiving member 8 of the food 10 after cutting. A gear 102 is fixed to the output shaft of the motor 101, and the gear 102 meshes with the gear 32. The gear 32 has a shaft 31 as a rotation center as in the above-described embodiment, and a link arm 30 having the shaft 31 as a rotation center is fitted to the shaft 31. A slip mechanism is provided between the link arm 30 and the gear 32 as in the above embodiment. The link arm 30 is linked to the sliding member 89 by a long hole and a pin as in the above embodiment, and the sliding member 89 is coupled to the receiving member 8 substantially integrally. The drive mechanism from the motor 101 to the link arm 30 constitutes the second drive mechanism.
　モータ１０１を駆動源とするリンクアーム３０の回転範囲は、下側のストッパ３５と上側のストッパ３６で規制される摺動部材８９の摺動範囲よりも十分大きな摺動範囲を得ることができる回転範囲に設定され、摺動部材８９が上下のストッパ３６，３５に当接してもなおリンクアーム３０に加えられる回転駆動力は、上記滑り機構によって逃がされるようになっている。 The rotation range of the link arm 30 that uses the motor 101 as a drive source is a rotation that can obtain a sliding range sufficiently larger than the sliding range of the sliding member 89 regulated by the lower stopper 35 and the upper stopper 36. Even if the sliding member 89 is in contact with the upper and lower stoppers 36 and 35, the rotational driving force applied to the link arm 30 is released by the sliding mechanism.
　図３５に示す実施例において、図示の初期位置にある食品載置台５に巻き寿司のような食品１０を載置してスタートボタンを押すと、モータ６１が起動されて食品載置台５が食品１０とともに姿勢を変えながら斜め下方に向かって移動する。その間、切断刃３によって食品１０が複数個に切断される。この切断行程の途中からモータ１０１が起動され、ギヤ１０２，３２を経てリンクアーム３０が反時計方向に駆動され、摺動部材８９がストッパ３６に当接する位置まで移動してモータ１０１が停止する。摺動部材８９と一体の受け部材８も斜め上方に移動して、切断される食品１０を受け取る態勢をとる。 In the embodiment shown in FIG. 35, when a food 10 such as rolled sushi is placed on the food placing table 5 in the illustrated initial position and the start button is pressed, the motor 61 is activated and the food placing table 5 is moved to the food 10 At the same time, it moves diagonally downward while changing its posture. Meanwhile, the food 10 is cut into a plurality of pieces by the cutting blade 3. The motor 101 is started in the middle of the cutting process, the link arm 30 is driven counterclockwise through the gears 102 and 32, and the motor 101 stops by moving to a position where the sliding member 89 contacts the stopper 36. The receiving member 8 integrated with the sliding member 89 also moves obliquely upward, and is ready to receive the food 10 to be cut.
　食品１０の切断が完了した時点では、食品１０が受け部材８の受け取り部８２に食品１０が受け渡され、食品１０のサイズの大小に応じて受け部材８が下方に押される。この押し下げ力により上記滑り機構が滑り、リンクアーム３０、摺動部材８９および受け部材８が押し戻される。 When the cutting of the food 10 is completed, the food 10 is delivered to the receiving portion 82 of the receiving member 8, and the receiving member 8 is pushed downward according to the size of the food 10. The pushing mechanism causes the sliding mechanism to slide, and the link arm 30, the sliding member 89, and the receiving member 8 are pushed back.
　駆動アーム６５が食品１０を切断するのに必要な角度回転駆動されると、次にモータ６１の回転方向が逆向きに切り換えられ、食品載置台１０は初期位置に復帰する。また、モータ１０１も逆向きに回転駆動され、摺動部材８９がストッパ３５に当接するまでリンクアーム３０が時計方向に回転駆動され、モータ６１の駆動が停止する。このとき、受け部材８は食品の取り出し部にあり、受け部材８の上に所定の姿勢を保って支持されている切断済みの食品１０を能率よく取り出すことができる。 When the drive arm 65 is driven to rotate at an angle necessary to cut the food 10, the rotation direction of the motor 61 is switched to the opposite direction, and the food mounting table 10 returns to the initial position. The motor 101 is also rotated in the reverse direction, the link arm 30 is rotated in the clockwise direction until the sliding member 89 contacts the stopper 35, and the driving of the motor 61 is stopped. At this time, the receiving member 8 is in the food take-out portion, and the cut food 10 supported in a predetermined posture on the receiving member 8 can be efficiently taken out.
　次に、本発明に係る食品切断装置の第４の実施例について図３６乃至図３８を参照しながら説明する。この実施例は、切断後の食品処理作業効率を一層高めることができるように、前記実施例における受け部材８の構成を工夫したものである。図３６乃至図３８において、受け部材８の受け取り部８２は、長方形状の孔が形成されることにより、外周縁部だけを残した枠形になっている。この枠形の受け取り部８２には、樹脂などでできた食品容器２００を着脱することができるようになっている。図示の食品容器２００は、容器本体部分２０１と、容器本体部分２０１の一側縁部から一体に延び出ていて折り曲げることにより容器本体部分２０１の開口端を覆うことができる蓋２０２を有してなる。容器本体部分２０１は、食品を収容するための窪みと、窪みの開口縁部から外方に延びた鍔部を有している。上記受け取り部８２の孔に容器本体部分２０１を落とし込むことができるとともに、上記鍔部を受け取り部８２の枠によって支持することができるようになっている。上記受け取り部８２に容器本体部分２０１を装着するときの食品容器２００の向きは上記蓋２０２が前方に突出する向きとする。 Next, a fourth embodiment of the food cutting device according to the present invention will be described with reference to FIGS. In this embodiment, the structure of the receiving member 8 in the above embodiment is devised so that the food processing work efficiency after cutting can be further increased. 36 to 38, the receiving portion 82 of the receiving member 8 has a frame shape in which only the outer peripheral edge portion is left by forming a rectangular hole. A food container 200 made of resin or the like can be attached to and detached from the frame-shaped receiving portion 82. The illustrated food container 200 has a container body portion 201 and a lid 202 that integrally extends from one side edge of the container body portion 201 and can be folded to cover the open end of the container body portion 201. Become. The container main body 201 has a recess for containing food and a flange extending outward from the opening edge of the recess. The container main body portion 201 can be dropped into the hole of the receiving portion 82, and the flange portion can be supported by the frame of the receiving portion 82. The direction of the food container 200 when the container main body 201 is attached to the receiving portion 82 is the direction in which the lid 202 protrudes forward.
　その他の構成は第２の実施例又は第３の実施例と同様であり、食品の切断動作に連携して受け部材８が食品容器２００を支持したまま上下動する。したがって、受け部材８の受け取り部８２に食品容器２００を装着し、切断動作を開始させると、食品の切断動作に連携して食品容器２００とともに受け部材８が上昇し、切断済みの食品が食品容器２００に収容される。前記実施例について説明したように、受け部材８は、食品を受け取ると食品取り出し位置まで下降するので、食品容器２００を食品とともに取り出す。再び受け部材８に食品容器２００を装着して切断動作を開始させることにより、一連の切断動作を繰り返し行うことができる。 Other configurations are the same as those in the second embodiment or the third embodiment, and the receiving member 8 moves up and down while supporting the food container 200 in cooperation with the cutting operation of the food. Therefore, when the food container 200 is attached to the receiving portion 82 of the receiving member 8 and the cutting operation is started, the receiving member 8 rises together with the food container 200 in cooperation with the food cutting operation, and the cut food is the food container. 200. As described in the above embodiment, the receiving member 8 descends to the food take-out position when food is received, so that the food container 200 is taken out together with the food. By attaching the food container 200 to the receiving member 8 again and starting the cutting operation, a series of cutting operations can be repeated.
　受け部材８に食品容器２００を装着するかどうかは任意であるから、受け部材８の構成を任意に変更することができるようにしておくとよい。例えば、ユーザーの希望に沿うような各種アタッチメントを用意しておき、ユーザーはアタッチメントを交換することによって要求を満たすようにすることも可能である。 Since whether or not the food container 200 is attached to the receiving member 8 is arbitrary, it is preferable that the configuration of the receiving member 8 can be arbitrarily changed. For example, it is possible to prepare various attachments that meet the user's wishes, and the user can satisfy the request by exchanging the attachments.
　以上説明した各実施例では、切断刃が両持ち形式になっているが、本発明においては、切断刃が固定されていればよく、切断刃の固定形式は両持ち形式でも片持ち形式でもよい。 In each of the embodiments described above, the cutting blade is a double-sided type. However, in the present invention, the cutting blade may be fixed, and the fixed type of the cutting blade may be a double-sided type or a cantilever type. .
　本発明に係る食品切断装置は、主として海苔巻きなどの巻き寿司を主な対象食品として想定しているが、円柱状、角柱状、あるいは棒状の食品を輪切り状に切断するものであるから、切断対象となる食品は、巻き寿司のほか、蒲鉾、竹輪などの練り製品、その他の食品の切断にも使用可能である。 The food cutting device according to the present invention mainly assumes sushi rolls such as seaweed roll as the main target food, but cuts columnar, prismatic, or rod-shaped foods into round slices. The target foods can be used for cutting rolled sushi, kneaded products such as bamboo shoots and bamboo rings, and other foods.
